       Description:  The 3290 Information Panel uses IBM's plasma
panel technology for its display medium to provide a
large-capacity display that is distortion-free at every point on
the screen. The display image is formed by lighting cells (dots)
under the control of the display logic. The image is orange color
on a black background. There are two standard character sizes
formed as either 5 x 8 dot or 7 x 9 dot matrices. When the 5 x 8
character is used, the 3290 is capable of displaying 9,920
characters in a format of 62 rows x 160 columns. The large
display area allows the user to select multiple screen formats.
An alternate screen format, using the 7 x 9 dot character, allows
50 rows x 106 columns to be displayed.  The 3290 incorporates
screen-management facilities to allow the user to efficiently
interact and manipulate large amounts of information.
       The IBM 3290 is data stream compatible with all models of
today's IBM 3270 displays in alphameric application environments;
no programming changes are required for current alphameric
applications if hardware features used on the 3278/3279 are
available on the 3290.  It attaches to the IBM 3274 Control Unit
utilizing one physical terminal port and up to five addresses.
Your current applications can run unmodified. For large-screen
and business graphic applications, IBM software is available (see
programming support).
       The 3290 Information Panel provides new levels of 3270
usage through the following functions:
.  Concurrent multiple-screen capability. The viewing area can be
   configured to display up to four 3278 Model 2 screens, two
   3278 Model 3, 4, or 5 screens, a full page of computer output
   in printer format (62 rows x 132 columns), two horizontal
   screens of up to 31 rows x 160 columns, or two vertical
   screens of up to 62 rows x 80 columns.
.  Multiple screen-copy capability. One or more screens are
   interactive and the remaining configured screens can be used
   for copying of the interactive screen(s).
.  Multiple interactive screens. The end user may log-on to an
   application, multiple applications, or multiple systems.  Each
   configured screen acts like a separate display station,
   referred to as a logical terminal. The 3290 permits up to four
   logical terminals to be operable simultaneously in one
   physical 3290 terminal, utilizing one 3274 terminal port.
.  Multiple partitions. A screen can be divided into up to 16
   separately managed partitions via application program control
   with vertical scrolling capability in the 3290 display
   station.
.  Programmed symbols which are generated via symbol sets can be
   loaded into the six-character buffers via program control.
   Once loaded, the buffer positions can be addressed to create
   specific images on the screen. A composite of several images
   can be combined to create symbols or graphic patterns.
.  Screen management.  The IBM 3290 Information Panel brings to
   the end user a new level of screen management to facilitate
   the use of the large viewing area in a manner that is both
   easy to use and productive.
   Incorporated in the design of the 3290 Information Panel are:
   -   Control of 3290 Information Panel's screen configuration
       from the keyboard.
   -   Coexistence of multiple copy screens with multiple
       interactive screens.
   -   Keyboard control of the display of logical terminals,
       partitions, and cursor movement.
   -   Horizontal rule line under cursor control.
   -   Zoom
       The following paragraphs briefly describe these facilities
and their use.
       Screen configuration control:  The 3290 Information Panel
provides the operator with the facility to display 3270
applications in a variety of screen sizes and formats.  The
screen formats of the IBM 3278 Models 2 - 5 and the IBM 3279
Models 2 and 3 are displayable in single- or multiple-screen
configurations. For example:
four 3278/3279 Model 2 screens,
two 3278/3279 Model 3 screens,
two 3278 Model 4 screens, or
two 3278 Model 5 screens.
       In many cases, the 3278 Model 2 (1,920 characters) format
will be the primary format of the displayed data. This format,
consisting of 24 rows x 80 columns of alphameric data, can be
displayed on the 3290 Information Panel in the single screen
format or in up to four separate screens, simultaneously.  Screen
formats of 62 x 132 or two 31 x 132 characters are possible for
the display of computer generated reports. Screen formats of 62 x
80 or two 62 x 80 characters are possible for program development
applications or text applications.
       The end user can set up the 3290 Information Panel to
select the screen configuration that is desired. This is
accomplished by placing the terminal in "set-up" mode from the
keyboard. This mode allows the end user to configure the 3290's
viewing area as desired, i.e., screen copy areas, interactive
screen areas, screen splits, and dual/mono case display of
characters.
       Multiple screens: The 3290 Information Panel allows data
to be displayed in a flexible array of screen options. The 3290's
viewing area may be split into two equal horizontal areas, two
equal vertical areas, or four areas of equal dimensions. Each
area may be used to interact with host applications or the area
can be designated a copy area into which other areas may be
copied. These screen areas may be configured by the end user from
the keyboard.
       Screen area control: The 3290 Information Panel provides
the operator with the facility to move the cursor between
interactive screen areas to change a displayed area with one that
is off-screen, i.e., resident in the 3290's storage.
       Rule line: A rule line is provided to assist in eye
positioning and location of the displayed data.  The rule line
can, at the users option, be moved vertically with the cursor.
       Zoom: The 3290 Information Panel provides the facility to
enlarge the character size of either a partition or a displayed
screen to proportionally occupy the full viewing area.  (Caution:
care must be taken in the use of zoom when using programmed
symbols to avoid distortion of the displayed image.)
       Applications: The IBM 3290 Information Panel offers the
user several features that improve the efficiency of application
processing. The 3290 can concurrently display one of the
following screen formats:
four 3278/3279 Model 2 screens
two 3278/3279 Model 3 screens
two 3278 Model 4 screens
two 3278 Model 5 screens
       This viewing-area capacity, coupled with the end user's
ability to choose screen layouts, makes the 3290 Information
Panel a flexible work station for such applications as
presentation graphics, computer generated report retrieval,
program development, and multiple-screen data base applications,
e.g., copics, credit authorization.  (See programming support
section.)
       The multiple-screen facilities of the 3290 Information
Panel are transparent to host programming when existing 3278
application formats are used and no 3274 configuration
restrictions or hardware incompatibilities affect the application
(see 3270 compatibility). This transparency allows the 3290 to be
operated as compatible 3278 display(s) allowing the user to
obtain the advantages of the 3290 without reprogramming host
applications. In addition, the screen management facilities of
the 3290 make the work station easy to use and easily adaptable
to production use.
       Presentation graphics: The 3290 provides a flexible
terminal environment for the creation of pictorial displays in
the Presentation Graphics application. Utilizing the Graphical
Data Display Manager (GDDM) and Presentation Graphics feature
(PGF) 5748-XXH, the 3290 user can construct pictorial graphs and
charts for data presentation in one screen area while utilizing
up to three additional interactive screen areas for the retrieval
of the required data.  Using partitions to segment graphs and
data, a single application can provide a new level of data
analysis support with concurrent data and graphic update. The
3290 screen copy facility can be used to copy interim stages of a
graph's creation for comparison and to evaluate the effects of
changes in specified parameters, as long as new fonts are not
required.
       Computer generated report retrieval: The 3290's large
screen-capacity when used with the Report Management and
Distribution System (RMDS) programming RPQ (5799BHD) provides the
facilities for viewing full-page computer printed output (62-row
x 132-column). The user can view pages on a selected basis or
browse through the report page by page. Hard copy can be obtained
via the 3290 screen copy (print) facility. This use of the 3290
Information Panel facilitates significant reduction of the use of
paper and the handling of paper.
       Program development: The 3290 large screen and its screen
split options of multiple interactive or copy screens provides
the potential for improved programmer productivity. The 3290
permits the programmer using the available Interactive System
Productivity Facility (ISPF) and ISPF Program Development
Facility (ISPF/PDF) to browse through program listings and
computer output, reducing output turnaround time and output
printing or microfilming. The 3290 allows full-screen editing of
a large capacity screen (62 rows x 160 columns) permitting the
viewing of an entire module. Partitioning support in ISPF allows
more than a two-way split of the 3290 screen to allow program
listings, source code, compiler output, and test results to be
compared. The multiple-interactive-screen facility of the 3290
allows the end user to concurrently view program listings while
making corrections. For example, a 3278 Model 5 screen and a 3278
Model 2, using Edgar, can be operated concurrently.
       Large screen data base/data communication applications:
More information can be viewed concurrently by using the 3290
Information Panel. The 3290 large screen and new
screen-management facilities permits users of multiscreen
application programs to view multiple screens at the same time
for correlation and checking operations. Screens can be moved to
copy areas for subsequent comparison with other screens of the
same application. Screens may be compared with other screens of
other applications by using the 3290 as multiple terminals.
       End-user interactive applications: In addition to multiple
3278/3279 screen operations, the large-screen capacity and new
screen-management facilities of the 3290 allow full-screen
alphameric and graphic output and reduce scrolling requirements
significantly.
       Communications network management (CNM): The 3290 multiple
screen facility allows the system operator to display up to four
3278/3279 Model 2 screens concurrently and to selectively
interact with the desired screen. This mode of 3290 operation
provides a versatile system control console for the management of
computer networks.  Existing CNM applications, including NCCF,
NPDA, and NLDM, may use the 3290 Information Panel as an operator
station since the 3290 is compatible with existing 3270 device
support.
       Ergonomics: The IBM 3290 Information Panel has been
designed to provide the operator with a large-screen flicker-free
display presentation whose displayed characters are undistorted
and stable in all locations of the viewing area.
       The 3290 incorporates:
.  Up to 9,920 characters in a small footprint.  The dimensions
   of the 3290 Information Panel are 50.20 cm (19.7") in height,
   56.00 cm. (22.04") in width, and 30 cm. (11.81") in depth,
   with a keyboard attached via a 91.4 cm (36") cable. This
   compares with the 3278 dimensions of 48.26 cm (19") in height,
   43.18 cm (17") width, and 53.34 cm (21") in depth. The 3290
   weighs 31 kg (68.20 lbs), its keyboard weighs 3.4 kg (7.48
   lbs.).
.  A new anti-glare, smudge-resistant screen is provided.
.  Electromagnetic emission. The 3290 meets the FCC standards for
   Class A computing devices. There is no detectable X-ray or
   ultraviolet emission below 330 nm.
.  Adjustable tilt.  The 3290 Information Panel can be adjusted
   in tilt through 20 degrees (5 degrees forward to 15 degrees
   backward).
.  New keyboard.  A new light low-profile keyboard with
   inclination adjustment settings of 3.5 degrees, 12 degrees,
   and 17.1 degrees is attached via cable.  Cable attached
   numeric or program-function keypads are offered as optional
   features.
       3270 compatibility: The IBM 3290 Information Panel is a
member of the IBM 3270 display family. It provides 3270 data
stream compatibility with the 3278 and 3279 display stations and
the 8775 Display Terminal. There are operational differences in
terms of the screen management facilities, the new keyboard,
method of highlighting, and peripheral device attachment. For
performance differences, particularly in the binary synchronous
communications environment, see the performance section of this
letter.  The following paragraphs briefly describe the
compatibility characteristics of 3290 and its companion products.
       Hardware
.  System attachment. The 3290 Information Panel attaches to
   System/370, 30XX Processors, and 43XX Processors via the IBM
   3274 Control Unit (excluding Models 1B, 21A, 21B, 21C, 21D).
   All 3274 attachment environments are supported, i.e., SNA
   local channel, non-SNA local channel, synchronous data link
   control (SDLC) remote or binary synchronous control (BSC)
   remote. Attachment to the 3274 is by the same type of coax
   cable as 3278. The 3290 attaches to the 8100 via the IBM 3274
   Control Unit Model 51C or 61C.
.  3274 configuration support. The IBM 3274 Control Unit requires
   customizing to support the 3290 Information Panel. Two

   configuration support options (3274 Configuration Supports T
   and D) are available to support the attachment of the 3290
   Information Panel to the 3274 Control Unit. Configuration
   Support T is intended for initial implementation of the 3290
   environment. It requires 128K storage and supports all of the
   3290 functions. It does not support Category B terminals,
   extended color, programmed symbols (PS), X.21, and/or loop
   attachment. Configuration Support D provides support for these
   functions, except for Category B terminals.  Note: the IBM
   3290 supports programmed symbols (PS) independent of the
   configuration support being used. (See Planning information
   for additional detail.)
.  Category B device attachment. Category B devices (3277 Display
   Stations and their associated printers) cannot be mixed with
   3290 Information Panels on any 3274 configuration.
.  Data stream compatibility. The 3290 will accept the 3270
   (except triplane) data stream and supports the extended
   highlight and graphic (PS) data streams of the IBM 3278, 3279,
   and 8775 displays.
.  Printers. The 3270 printers support the 3290 Information Panel
   with print capability up to 132-character line lengths. The
   SNA character string (SCS), Specify #9660, is required on the
   3287.  The binary synchronous control copy command is not
   available with the 3290 Information Panel.  Presence of the
   3268 Specify #9181 will allow the IBM 3290 to utilize the
   save/restore format function during local copy operation. This
   provides enhanced forms integrity in a shared printer
   environment.
.  Peripheral device attachment. The 3290 Information Panel does
   not support attachment of magnetic readers or selector light
   pens.
.  Encryption/decryption. The 3290 Information Panel does not
   support encryption/decryption.
.  Color. The 3290 Information Panel is monochrome; it does,
   however, accept the 3270 data stream with color attributes for
   display.
.  Dual intensity highlighting. The 3290 Information Panel does
   not provide dual intensity.
.  Entry assist. The 3274 entry assist function is not available
   on the 3290 Information Panel.
.  ASCII.  ASCII 8 information interchange is available via RPQ.
       Software: The IBM 3290 is data stream compatible with all
models of today's IBM 3270 displays in alphameric application
environments.  Existing alphameric applications will run on the
3290 unmodified (in their current screen size).  No programming
changes are required of current alphameric applications unless
the program is affected by 3274 Control Unit configuraton
restrictions (i.e., no Category B terminals, 3279 extended color,
X.21, BSC copy, or programmed symbols) or required hardware
functions not available with the 3290 (i.e., magnetic readers,
ASCII, encryption/decryption, 8775/IDTF functions, color, dual
intensity highlighting, or selector light pen).
       The 3290 will accept 3270 data streams and supports
extended highlighting and graphics (PS).  The multiple screen
facilities of the 3290 can be used without any modifications to
system software.
       For large screen support, support for the partitioning and
vertical scrolling functions of the 3290 and business graphics
applications, IBM software is available (see programming support
section).
       Subsystems (see programming support section).
       Operating environments (see programming support section).
       Planning information
       Data security: Data security features provided by the 3290
are nondisplay field control and the security keylock.
Encryption/decryption is not available on the 3290. User
management is responsible for evaluating, selecting, applying and
implementing such features and for the appropiate administrative
and application controls.
       Installation: The IBM 3290 Information Panel is a customer
set-up machine.  It attaches to one terminal port and may have up
to five addresses associated with it on the IBM 3274 Control
Unit, depending on the application. The 3290 Information Panel is
3270 compatible in alphameric application environments; current
alphameric applications will run unmodified. Large screen support
and business graphics support are available from IBM (see
programming support). The 3290 Information Panel requires
customizing the 3274 Control Unit and a microcode load from the
3274 to support its operation (see prerequisites).
       Prerequisites: The IBM 3290 Information Panel attaches to
the IBM 3274 Control Unit Models 1A, 1C, 1D, 31A, 31C, 31D, 41A,
41C, 41D, 51C, and 61C. The 3290 requires the customizing of the
3274 and a microcode load from the 3274 to be operational.  A
3178, 3278, or 3279 display station with keyboard attached to
port 0 of the control unit is required for customizing and
maintenance of the 3274 Control Unit.
       There are two 3274 microcode-load options for support of
the 3290 Information Panel. For users who do not use Category B
devices (3277 Display Stations and associated printers), advanced
function (i.e., seven-color support of the 3279 Color Display
Station, extended highlighting, or programmed symbols .PS)
graphics), loop attachment, or X.21, Configuration Support T is
offered.  For customers who do not use Category B devices but do
use the advanced function support, Configuration D is available.
       When using either the Configuration Support T or D, the
IBM 3290 requires a microcode load from the IBM 3274 Control
Unit. This microcode is supplied with the Configuration Support T
diskette. An additional diskette, the IBM 3290 load diskette
(Specify #9301), is required with Configuration Support D.
       The following is a brief summary of the support options;
for more details, see the IBM 3274 Control Unit Product
Announcement dated March 8, 1983.
       Configuration Support T for the 3274 Control Unit (3274
Specify #9113) requires 128K byte storage and can be used on 3274
Control Unit Models 1A, 1C, 1D, and 51C (with 128KB storage) and
on Models 31A, 31C, and 31D. This support includes 3278 Models 2
- 5, 3279 four-color, APL, and all 3290 Information Panel
functions. Configuration support T does not support Category B
devices (i.e., 3277 Display Stations), loop attachment, X.21, or
programmed symbols (PS). Note: PS is available on the 3290 when
Configuration Support T is in use.
       Configuration Support D for the 3274 Control Unit provides
extended 3270 data stream function support (which includes
seven-color support for the 3279 Color Display Station,
programmed symbols set .PS) graphics, and extended highlighting)
in addition to 3278 Models 2 - 5 and APL support. Configuration
Support D is standard on 3274 Control Units  Models 41X and 61C.
Users with control units of the Model 31X  and/or Model 51C must
order an Integrated Diskette Drive Enhancement (#3101 and/or
#5101 respectively) and an Extended Function Store Type C1
(#3650).
       Note: On the Models 31X and 51C, this configuration cannot
be customized to support Category B devices, i.e., 3277 Display
Stations when the 3290 Information Panel is to be customized at
the same time. To support the 3290 Information Panel, the 3290
Load Diskette (#9301) is required.
       Note: Configuration support T is provided to allow users
to use the 3290 Information Panel for initial implementation in
their environment with minimum effect on the 3274.  Configuration
T will not be upgraded. For long term use, Configuration Support
D should be used.
       Maximum number of 3290 terminals attached to the 3274
Control Unit:  The multiple-logical-terminal facility of the 3290
allows the user to designate up to five terminal addresses in a
single IBM 3290 Information Panel. This requires one primary and
four logical addresses for one physical port on the 3274 Control
Unit.  When planning installation of the 3290, consideration must
be given to the number of logical and physical addresses that are
planned to be used compared with the maximum number of addresses

and ports that are available. The number of addresses and ports
available is dependent on the model of the 3274 Control Unit and
the method of system attachment.
       When using the multiple-logical-terminal capability of the
3290, Configuration Support D allows 3178/3278/3279 display
stations and/or associated printers to be intermixed with 3290s
on a 3274 Control Unit. The multiple-logical-terminal environment
of the 3290's is maintained, providing the display stations
and/or associated printers are attached to ports that have been
defined for multiple logical terminals at customization time.
       When using Configuration Support T, 3290s must be attached
to contiguous 3274 ports if the multiple-logical-terminal
environment is to be maintained for all the 3290s.
       Table A specifies the maximum number of logical and
physical terminals that can be attached to the 3274 Control Unit
when using the multiple-logical-terminal facility.

       Performance: The IBM 3290 Information Panel is equipped
with its own microprocessor for processing inbound and outbound
messages and managing the display of information on the large
screen. This processing capability of the IBM 3290 lessens the
processing load on the IBM 3274 Control Unit when compared with
the attachment of an IBM 3278 or 3279 display station.  With the
IBM 3290, system response times are less dependent on the number
of 3290s attached and on the transaction load on the 3274 Control
Unit. Where subsystem transaction loads limit the number of IBM
3278 or 3279 display stations that can be attached, it will be
possible to attach larger numbers of 3290s.
       Although 3290/3274 subsystem response times are less
dependent on 3274 transaction loads, there are many cases in
which the response of the 3290/3274 is slower than 3278/3279/3274
configurations due to data stream processing or increased network
loads caused by the additional logical terminals.  Subsystem
response for the IBM 3290 is commensurate with message length but
generally less dependent on data stream content.
       Care should be taken in planning the installation of 3290
Information Panels to determine the optimum configuration
requirements, especially in the binary synchronous (BSC)
communications environment. NCP BSC line utilization may be
increased significantly while the NCP is waiting for the 3290
data stream processing to be completed. Where line utilization is
very high in existing networks, additional lines should be
considered.
       Applications using long unblocked records in the binary
synchronous control (BSC) environment must restrict the record
length to less than 7,000 bytes. Messages employing blocking
should adhere to a 3,500-byte maximum block size and should only
be added to the network after careful planning. When these
applications exist, consideration must be given to line speed
(9,600 bps or above preferred), application load, performance
requirements, network limitations, and usage patterns. These
applications should be limited to testing and/or to
limited-period migration. It is recommended that large screen
application usage for the new 3290 Information Panel be planned
for SDLC networks.

Site Preparation
       Programming support: Existing 3270 alphameric programs
will run unmodified on a properly configured 3290 Information
Panel.  For business graphics applications, Graphical Data
Display Manager (GDDM) Release 3 is required.  The new 3290
facilities of multiple copy screens and multiple application
screens require no changes to existing alphameric host programs.
Host copy operations are available under SDLC attachments but are
not available under binary synchronous attachments. Local
printing of screen information to printers attached to a common
3274 Control Unit is supported under all host attachments.
       Full-screen support (i.e., 62 x 160 character screen
addressing) requires 14- or 16-bit addressing support for the
3270 data stream. Either form of addressing requires new host
programming support.  Graphics, partitioning, and scrolling also
require new host programming support.
       Programs for System/370, 30XX Processors, 4300 Processors,
and 8100 Information Systems which will support the 3290
Information Panel beyond the multiple interactive screen  and
multiple copy screen compatibility modes are briefly described in
the following paragraphs. The dates shown in parentheses indicate
when the supporting product release will be available. Where PTFs
are required for particular program releases, the PTF numbers can
be obtained from your marketing representative*.
*  Marketing representatives may obtain these through the EQUAL
   system.
       See the table included with this announcement (3290
System/Access Method/Subsystem Programming Support) for a summary
of the system access method support of the 3290.
       CICS (V1R6 OS is available, DOS 6/83)
       The 3290 Information Panel large-screen support, screen
partitioning and vertical scrolling will be available through

enhancements to the terminal control program interface and basic
mapping support (BMS) components of CICS. These enhancements will
be available in CICS/VS Version 1, Release 6.
       CICS/VS 1.6 support for the 3290 Information Panel is
restricted when using binary synchronous communication (BSC)
protocols. Caution:  very large messages (typically exceeding
3,500 bytes) should not be sent as single messages.
       Previous releases of CICS/VS (prior to Release 1.6) will
allow 3290 Information Panel operation with certain functional
limitations. Namely, the large screen capability is not
supported; the maximum number of partitions allowed is 8; there
is no basic mapping support (BMS) for partitions or vertical
scrolling for Releases prior to 1.6.
       SDF/CICS
       SDF/CICS will be extended to provide map definition for
the large screen, partitioning and vertical scrolling functions
of the IBM 3290 Information Panel.
       IMS/VS (V1R3 4Q 83)
       IMS/VS will support the 3290 large-screen function in
Version 1 Release 3 through extensions to message format services
(MFS). Releases of IMS/VS prior to 1.3 support the 3290
Information Panel as one or more 3278 Model 2, 3, 4, or 5
displays. The MFS support of large-screens does not apply to 3290
partitions or scrolling.
       BTS (PTF 3/83)
       The IMS Batch Terminal Simulator licensed program will be
extended via PTF to support the large screen capability of the
3290. This support is consistent with that provided in IMS/VS
Version 1 Release 3.
       ACF/VTAM (available)
       Version 1 Release 3 will support 3290 data streams under
MVS, VS1 and DOS/VSE systems.
       Version 2 Release 1 will provide support for 3290 data
streams under MVS, MVS/XA, VS1, and DOS/VSE systems. New support
will provide message chaining for SDLC-attached devices by using
large message performance enhancement outbound. VTAM does not
support the transmission of large messages to BSC attached
devices. Records over 7,000 bytes are restricted in
BSC-attachments. Records over 3,500 bytes are not advised in BSC
attachments.
       For ACF/VTAM SNA support, some performance improvements
may be possible for applications operating on ACF/VTAM Version 2
by using the large message support API enhancements.
       In multi-domain networking environments, ACF/VTAM non-SNA
channel support through 3274 Control Units Models 1D, 31D, and
41D is restricted to multiple application screen and multiple
copy screen operation.  Screen sizes beyond that of the 3278
Model 5 (3,564 characters) are not supported. This restriction is
removed in single domain environments.
       ACF/VTAME (available)
       ACF/VTAME will support the advanced function capabilities
of the 3290 Information Panel in DOS/VSE only for SNA
environments.
       ACF/TCAM (available)
       ACF/TCAM Version 2 Release 4 will support the 3290 in MVS,
MVS/XA and VS1 for SNA/SDLC, and local SNA and local non-SNA
attachments. Support for binary synchronous communications 3290
attachments is provided through attachment to ACF/NCP. BSC
attachment via EP is not supported except in support of the 3290
as a 3278-compatible display. Records over 7,000 bytes are
restricted in BSC attachments. Records over 3,500 bytes are not
advised in BSC attachments.
       In multi-domain networking environments, ACF/TCAM non-SNA
channel support through 3274 Models 1D, 31D, and 41D is
restricted to multiple application screen and multiple copy
screen operation. Screen sizes beyond that of the 3278 Model 5
(3,564 characters) are not supported. This restriction is removed
in single domain environments.
       The ACF/TCAM V2R4 subsystem interface does not support the
large message performance enhancements that are supported by
ACF/VTAM Version 2. In this regard, the TCAM subsystem interface
support for the 3290 is comparable to that provided by ACF/VTAM
Version 1 Release 3.
       ACF/NCP (available)
       ACF/NCP Version 1 Release 2.1, Version 1 Release 3,  and
Version 2 will support the IBM 3290 Information Panel in a manner
compatible with ACF/VTAM and ACF/TCAM. In binary synchronous
(BSC) attachments to ACF/NCP, support is restricted to functional
compatibility with 327X Models 2 - 5 display stations. Records
over 7,000 bytes are restricted in BSC attachments. Records over
3,500 bytes are not advised for BSC attachments.
       NCCF (available)
       NCCF supports the IBM 3290 Information Panel as a Network
Management console when the IBM 3290 is defined as a 3278 Model 2
display.
       BTAM (MVS,VS1), BTAM-ES, BTAM/SP (available)
       Applications may transmit large-screen and screen
partitioning specifications via 3290 data streams transparent to
BTAM.  For remote operation, applications must use BTAM binary
synchronous (BSC) transparency macros. It is recommended that BSC
text blocking be used by applications to manage the large data
streams of large screen support.
       TSO, TSO ACF/VTAM (PTF 3/83),  TSO ACF/TCAM (PTF 8/83)
       TSO using ACF/VTAM Version 2 Release 1 or using ACF/TCAM
Version 2 Release 4 provides 3290 Information Panel large-screen
support. Each environment requires an appropriate PTF.
       VM/SP, VM/SP Systems Product Editor, (PTF 12/83)
       Large screen support for the 3290 Information Panel will
be provided in Release 3 of VM/SP, including VM/SP System Product
Editor support. This support is provided via PTF and results in
the ability to create and display files to a maximum page size of
62 X 160 characters. A suggested use of this capability is to run
two application terminals, each with dimensions of 62 X 80
characters. In the first of these terminals, source text files
may be created and edited, and in the other, formatted output
from the Document Composition Facility (DCF) may be viewed.
Another suggested use in the program development process is to
create and edit source files in one application terminal while
viewing object code files in the other. Thus, both program
development and text operations are both significantly enhanced
in the VM/SP environment.
       GDDM R3, CICS/VS 7/83, IMS/VS 7/83, TSO/VS 7/83, VM/SP
7/83, VSPC 7/83
       Release 3 of GDDM will provide 3290 Information Panel
support  for large screen, partitioning, and vertical scrolling.
All GDDM Interactive Map Definition (IMD), Presentation Graphics
Feature (PGF) alphamerics and graphics functions are available
for the IBM 3290.
       Enhancements have been added to allow full utilization of
the 3290 Information Panel's functional capabilities. GDDM,
including IMD, will allow an application to create and manage up
to 16 partitions, each with its own cell size and scroll buffer.
Partition management functions will allow an application to
create and delete partitions and to modify viewports associated
with partitions.
       Several of the application programs supporting the 3290
achieve their support through the use of GDDM. These include ADRS
II, APL DI, SLR, VSAPL, VSPC, EPS, 3-D PGF, and PLANCODE I.
(Caution: previous releases of GDDM will support 3290 alphameric
capabilities, but previous GDDM releases will not support 3290
graphics. Release 3 of GDDM is required to support 3290
graphics.)
       GDDM supports the 3290 in several different host
environments (CICS/VS, IMS/VS, TSO, VM/370 SP, and VSPC.) When
GDDM Release 3 is installed in any of these environments, it
supports graphical output to 3278-compatible screen size
configurations of the 3290.  Note that via GDDM Release 3, the
support of full 3290 function is also available in current
versions of these environments. Please consult the GDDM Release 3
announcement material to establish the environment release levels
in which GDDM fully supports 3290 function.
       ISPF
       ISPF will be extended to provide application development
support plus dialog management support of the 3290 large screen.
Horizontal and vertical splitting will be provided allowing the

user to run four dialogs simultaneously.  Also, provisions will
be made for users of ISPF to introduce graphics fields in their
output panels. This is accomplished through the graphics services
provided in GDDM Release 3.
       8100 DPPX/DPS V2 (available)
       DPPX/DPS V2 provides support for screen sizes up to those
supported by 3278 and 8775. Provided that the 3290 is configured
exactly as one of those devices, it provides support for
partitioning and scrolling up to the limits of the 8775. DPPX/DPS
V2 does not provide mapping support for variable character cell
sizes, but it does allow for application generated support for
this capability.
       Report Management and Distribution System Release 1.1 TSO
available, CICS 3Q 83, IMS 4Q 83
       The Report Management and Distribution System Programming
RPQ is a series of programs that provide the MVS user with a
system to store, to protect, to view, and to print reports on
demand that are currently produced on paper or microfiche.
Version 1 Release 1.1 of the Report Management and Distribution
System will exploit the large screen, partitioning, and vertical
scrolling capabilities of the 3290.
       The Report Management and Distribution System exploits the
3290 in two different ways.  First, if the full 3290 screen is
made available to the Report Management and Distribution System
it will partition the screen in such a way that, in addition to
header information, 58 lines of a full 132 character-wide page of
'printed' output will be displayed, in coexistance with separate
partitions that present prompt/help information and that allow
for the specification of document viewing commands.  The
prompt/help partition is operator scrollable using the vertical
scrolling capability of the 3290. The 3290 will display up to 160
character-wide reports without other partitions.
       Second, if the 3290 screen is subdivided into two logical
terminals via the multiple interactive screen capability, with
one of these screens being positioned above the other on the
physical display surface, the Report Management and Distribution
System will exploit the wide screen capacity of its half of the
3290. Report pages will be displayed in the Report Management and
Distribution System screen along with either prompt/help
information or a viewing command input area. If the report line
length is less than 133 characters, a second partition containing
header hold information will also be displayed. The non-displayed
portion of each report page will be accessable to the Report
Management and Distribution System operator via scrolling. This
method of Report Management and Distribution System operation
with the   3290 multiple screen capability might be used to allow
concurrent reference to two different reports (by exercising the
Report Management and Distribution System twice - one in each
section of the 3290 screen) or possibly to allow viewing of a
single report while data base update or reference operations are
taking place in the other portion of the 3290 screen.
       The Report Management and Distribution System operates
with MVS 3.7 or later with SU 32 (System Security Support, if
desired), JES2 or JES3, ACF/VTAM Version 1 Release 3 or later,
OS/VSAM, SPF/MVS (5668-009), or ISPF (5668-960). TSO support is
included in these requirements. IMS support for the 3290 is
provided with IMS/DC (5740-XX2) Version 1 Release 3. CICS support
is provided with Report Mangement and Distribution System Version
1 Release 1.1 and CICS (5740-XX1) Version 1 Release 6.
       ICCF (available)
       VSE/ICCF is a DOS/VSE based interactive system designed to
allow multiple terminal users to perform a variety of tasks
concurrently. ICCF Release 3 supports the IBM 3290 as a 3278
Models 2 - 5 compatible display.
       DCF (available)
       The IBM Document Composition Facility (DCF) and the
Foreground Environment feature support the 3290 only in 3278
Models 2 - 5 compatability mode.
       When the 3290 large screen capabilities are exercised,
documents entered via the appropriate editor (VM/SP System
Product Editor or ISPF) are built with logical page sizes up to
62 lines long and 132 characters wide. Using the FILE option of
DCF, a formatted document can then be produced that is
displayable on the 3290 through the VM/SP System Product Editor
or through ISPF. DCF will be available in both the TSO and the
VM/SP environments.
       PROFS (V1 8/83)
       The IBM Professional Office System (PROFS) licensed
program supports the IBM 3290 as a 3278 Models 2 - 4 display when
the 3290 is defined to VM/SP as a 3278 Models 2 - 4 display.
       ADRS II (available)
       A Departmental Reporting System II is an APL application
for the creation of reports. Users of Release 1.8 with
appropriate SECOM will be allowed to create 3290 Information
