The CSVDYNEX LIST request returns information about all exits in
the system that have been defined to the dynamic exits facility, or
about specific exits (EXITNAME parameter). The information returned
includes: - The definition of the exit established on the DEFINE request,
including:
- Addressing mode
- Reentrancy
- Whether FASTPATH processing applies to the exit
- Whether the exit has been explicitly or implicitly defined.
- Characteristics of the exit routines associated with the exit,
as specified on the ADD request:
- Name of the exit routine
- State of the exit routine
- Whether jobname filtering was requested
- Whether STOKEN filtering was requested
- The STOKEN and JOBNAME, if provided.
The system returns the information in an area you provide (ANSAREA
and ANSLEN parameters), which is mapped by the CSVEXAA mapping macro.
Environment
The requirements for the caller are:

| Control parameters: |
Control parameters and the area where the system
places the information obtained through the CSVDYNEX LIST request
(ANSAREA parameter) must be in the primary address space or, for AR-mode
callers, must be in an address space or data space that is addressable
through a public entry on the caller's dispatchable unit access list
(DU-AL). |
Programming requirements
Include the CSVEXRET mapping macro to define symbolic names and
associated values for return and reason codes returned by CSVDYNEX.
Also include the CSVEXAA mapping macro to get a mapping of the output
area specified by the ANSAREA parameter. (See z/OS MVS Data
Areas in z/OS Internet Library at http://www.ibm.com/systems/z/os/zos/bkserv/.)
Restrictions
The caller must not have functional recovery routines (FRRs) established.

Parameters
The parameters are explained as follows:
- REQUEST=LIST
- Lists information about one or more exits.
- ,EXITNAME=ALL_EXITS
- ,EXITNAME=exitname
- EXITNAME=ALL_EXITS, the default, tells the system to list information
about all exits in the system that have been defined to the dynamic
exits facility.
EXITNAME=exitname specifies
a 16-byte field (or a register containing the address of a 16-byte
field) that contains the 16-character name of the exit. If the name
contains fewer than 16 characters, left-justify the name and pad the
field with blanks. To indicate the name of more than one exit, use
an asterisk for the last non-blank character. A matching exit name
is one that matches all the characters preceding the asterisk. If
the first character of the name is X'00', the system processes
the request as if EXITNAME=ALL_EXITS has been specified.
- ,ANSAREA=ansarea
- This parameter specifies an area (or a register containing the
address of an area) where the system is to store information associated
with the exits. Use the CSVEXAA mapping macro to map this area. (See z/OS
MVS Data Areas in z/OS Internet Library at http://www.ibm.com/systems/z/os/zos/bkserv/.)
Specify the length of this area on the ANSLEN parameter.
- ,ANSLEN=anslen
- Specifies a fullword (or a register containing the address of
a fullword) that contains the length of the area where the system
is to return the list. This value must be equal to or greater than
the length of the EXAAHDR structure in the CSVEXAA mapping macro.
If
the area is not long enough to contain all the information, the system
returns as many entries as it can. The system returns the length
that is currently required to contain all the information in the EXAAHTLEN
field in the CSVEXAA mapping macro, with return code CSVDYNEXRC_WARN
(4) and reason code CSVDYNEXRSNNOTALLDATARETURNED (X'xxxx0403').
- ,EXAAVER=0
- ,EXAAVER=1
- Specifies the format of information to be returned, as mapped
by DSECTs within the CSVEXAA data area. EXAAVER=1 returns more information
about exit routines than EXAAVER=0. Both EXAAVER=1 and EXAAVER=0
return header information mapped by the EXAAHDR DSECT, and exit information
mapped by the EXAAE DSECT.
- EXAAVER=0, the default, specifies that exit routine information
is mapped by the EXAAM DSECT.
- EXAAVER=1 specifies that exit routine information is mapped by
the EXAAM1 DSECT.
- ,EXITTYPE=ANY
- ,EXITTYPE=INSTALLATION
- ,EXITTYPE=PROGRAM
- ,EXITTYPE=NOTPROGRAM
- When REQUEST=LIST is specified, EXITTYPE is an optional parameter
that indicates the type of exit about which to return data.
The
default is EXITTYPE=ANY
EXITTYPE=ANY indicates that data is
returned for any exit type.
EXITTYPE=INSTALLATION indicates
that data is returned only if the exit is marked as an installation
exit.
EXITTYPE=PROGRAM indicates that data is returned only
if the exit is marked as a program exit.
EXITTYPE=NOTPROGRAM
indicates that data is returned only if the exit is not marked as
a program exit.
- ,RETCODE=retcode
- Specifies a fullword (or a register) where the system is to store
the CSVDYNEX return code. The return code is also in GPR 15.
- ,RSNCODE=rsncode
- Specifies a fullword (or a register) where the system is to store
the CSVDYNEX reason code. The reason code is also in GPR 0.
- ,MF=S
- Specifies the standard form of the CSVDYNEX macro.
