High Level Assembler for z/OS®, z/VM®, and z/VSE® V1.6 adds new capabilities to simplify
application programming, maintenance, and enhancement tasks. Among these are:
-
A HLASM Services Interface delivers important operating system environment services to let you write
platform-independent exits and external functions.
-
Suffix tags for instruction mnemonics let you use identically-named macro instructions and machine
instructions in the same source program.
-
Two new address constants provide resolution into long-displacement format, increasing instruction
addressability and reducing the need for additional instructions.
-
Many enhancements to the previous release are now fully integrated and documented.
Back to top
High Level Assembler for z/OS, z/VM, and z/VSE V1.6 is designed to execute on a broad range of
processors and operating system families. For specific prerequisites, refer to the
Technical information
section.

Back to top
High Level Assembler for z/OS, z/VM, and z/VSE V1.6 extends the capabilities of previous releases of
High Level Assembler. Among the enhancements are:
-
An internal
HLASM Services Interface
allows user exits to allocate and free storage, to write operator messages, and to access date and
time information, enabling you to write exits without operating system-dependent instructions.
-
To eliminate possible conflicts between identically-named macros and machine instructions, High
Level Assembler supports suffix tags for operation mnemonics. If you need to use a macro and a
machine instruction named XXX in the same source program, you may add tags to the mnemonic to
indicate the desired resolution, as in this example:
XXX A,B,C Invokes either the macro or machine
instruction, whichever is most recently
defined
XXX: MAC A,B,C Always invokes macro XXX
XXX: ASM A,B,C Always invokes assembler instruction XXX
-
To enable wider use of long-displacement instructions, High Level Assembler adds the QY-type and
SY-type address constants, which resolve their operands to signed 20-bit displacements.
-
The ambiguous result of using an Opcode attribute reference (O') in non-conditional assembly
statements is avoided by limiting such references to conditional assembly statements.
-
Among items introduced in the service stream for Release 5 are
-
Support for external declaration of PART symbols
-
Support for z9-109 instructions and the new ZS3 sub-option for the OPTABLE option
-
Support for z10 instructions and the new ZS4 sub-option for the OPTABLE option
-
Support for z9 decimal floating-point and other instructions
-
Support for three decimal floating-point data types
-
Improvements to the FLAG(PAGE0) option, to better diagnose unintended references to low storage
-
Ability to add the OPTABLE operand to the ACONTROL statement to allow localized control over
mnemonic resolution
-
Support for unsigned fixed-point binary constants
-
Insignificant leading zeros may be specified on decimal, binary, and hexadecimal self-defining terms
-
Clarification of symbol-table information for qualifier symbols
-
Support for new z9 instructions
-
Integrated support for all System z instructions, including those for the z10 series of processors
-
New diagnostics that help programmers create more reliable programs
-
The High Level Assembler for Linux on System z Feature supports assembling on IBM Linux for System
z. Source, macro, and COPY files can be in single-byte ASCII or EBCDIC, and traditional or Linux
ELF object files can be generated.

Hardware requirements
High Level Assembler for z/OS®, z/VM®, and z/VSE® V1.6 requires processors supporting
Architecture Level Set 1 (ALS-1). It also requires approximately 800K of central storage, and
selected features execute under z/OS, z/VM, z/VSE, Linux™ for System z™, and Windows®.
The Program Understanding Tool component of the High Level Assembler Toolkit Feature V1.6 requires a
workstation capable of running on Windows 95, NT, XP, or Vista with a minimum of 32 MB memory (64 MB
recommended) and at least 20 M of available hard-drive space, an SVGA display configured for at
least 256 colors, and a host-system connection or other means of transferring host files to the
workstation.
High Level Assembler for z/OS, z/VM, and z/VSE V1.6 executes under z/OS, z/VM, z/VSE, and Linux for
System z.
-
z/OS: V1R6, and later (5694-A01)
-
z/VM: V5R2, and later (5741-A05)
-
z/VSE: V3R1, V4, and later (5686-CF8)
Compatibility
High Level Assembler for z/OS, z/VM, and z/VSE V1.6 is upwardly compatible with previous
releases of High Level Assembler, with two possible exceptions:
-
Opcode Attribute references (O') may be made only in conditional assembly statements.
-
New machine instruction mnemonics may conflict with the names of existing customer macros. Such
conflicts may be avoided by choosing an appropriate OPTABLE option, or by using the mnemonic tagging
syntax introduced in this release.
User group requirements:
This announcement satisfies or partially satisfies 8 requirements from one or more of the
worldwide user group communities. Groups include COMMON, COMMON Europe, Guide Share Europe (GSE),
InterAction (Australia/New Zealand), Japan Guide Share (JGS), SHARE Inc, and other requirement

IBM has transformed its delivery of hardware and software support services to help you achieve
higher system availability. Electronic Services is a Web-enabled solution that offers an exclusive,
no-additional-charge enhancement to the service and support available for IBM servers. These
services are designed to provide the opportunity for greater system availability with faster problem
resolution and preemptive monitoring. Electronic Services comprises two separate, but
complementary, elements: Electronic Services news page and Electronic Services Agent.
The Electronic Services news page is a single Internet entry point that replaces the multiple entry
points traditionally used to access IBM Internet services and support. The news page enables you to
gain easier access to IBM resources for assistance in resolving technical problems.
The Electronic Service Agent™ is no-additional-charge software that resides on your server. It
monitors events and transmits system inventory information to IBM on a periodic, client-defined
timetable. The Electronic Service Agent automatically reports hardware problems to IBM. Early
knowledge about potential problems enables IBM to deliver proactive service that may result in
higher system availability and performance. In addition, information collected through the Service
Agent is made available to IBM service support representatives when they help answer your questions
or diagnose problems. Installation and use of IBM Electronic Service Agent for problem reporting
enables IBM to provide better support and service for your IBM server.
