Service summary

z/OS MVS Programming: Authorized Assembler Services Reference SET-WTO
SA23-1375-00

Table 1 lists services described in the following:
For each service, the table indicates:
  • Whether a program in AR ASC mode can issue the service
  • Whether a program in cross memory mode can issue the service
  • Whether the macro checks the SYSSTATE global macro variables
  • Whether the macro can be issued in 64-bit addressing mode
Note:
  1. A program running in primary ASC mode when PASN=HASN=SASN can issue any of the services listed in the table.
  2. Cross memory mode means that at least one of the following conditions is true:
    PASN¬=SASN
    The primary address space (PASN) and the secondary address space (SASN) are different.
    PASN¬=HASN
    The primary address space (PASN) and the home address space (HASN) are different.
    SASN¬=HASN
    The secondary address space (SASN) and the home address space (HASN) are different.

    For more information about functions that are available to programs in cross memory mode, see z/OS MVS Programming: Extended Addressability Guide.

  3. Callable services do not check the SYSSTATE or SPLEVEL global variables.

Notes:
  1. Primary mode callers can use either macro in the following macro pairs:
    • ATTACH or ATTACHX
    • SDUMP or SDUMPX
    • SYNCH or SYNCHX

    IBM® recommends that programs in AR ASC mode use the X-macros (ATTACHX, SDUMPX, and SYNCHX). If, however, a program in AR mode issues ATTACH, SDUMP, or SYNCH after issuing SYSSTATE ASCENV=AR, the system substitutes the corresponding X-macro and issues a message telling you that it made the substitution.

  2. CALLRTM TYPE=MEMTERM can be issued in cross memory mode. For CALLRTM TYPE=ABTERM, see the CALLRTM macro description.
  3. The only programs that can use ESTAE are programs that are in primary mode with (PASN=HASN=SASN).

    IBM recommends you always use ESTAEX unless your program and your recovery routine are in 24-bit addressing mode, or your program requires a branch entry. In these cases, you should use ESTAE.

  4. IBM recommends that AR mode callers use the STORAGE macro instead of using GETMAIN or FREEMAIN.
  5. For HSPSERV SREAD and HSPSERV SWRITE, PASN=HASN=SASN for a non-shared standard hiperspace for which an ALET is not used (that is, the HSPALET parameter is omitted).
  6. If you use the HSPALET parameter, the HSPSERV macro checks SYSSTATE.
  7. If the input UCB is captured, the IOSCAPF, IOSCMXA, IOSCMXR, and IOSDCXR macros can be issued in cross memory mode only if the UCB is captured in the primary address space. IOSCAPU CAPTOACT without the ASID parameter also can be issued in cross memory mode if the UCB was captured in the primary address space. IOSCAPU CAPTUCB and IOSCAPU UCAPTUCB cannot be issued in cross memory mode.
  8. PGSER can be issued in AR ASC mode only if you specify BRANCH=Y. PGSER can be issued in cross memory mode only if you specify BRANCH=Y or BRANCH=SPECIAL.
  9. Both SDUMP and SDUMPX can be issued in cross memory mode only if you specify BRANCH=YES.
  10. Only TIMEUSED LINKAGE=SYSTEM can be issued in AR ASC mode. TIMEUSED LINKAGE=BRANCH cannot be issued in AR ASC mode.
  11. For a QUERY request, CSVAPF can be issued only in primary mode. For all other requests, CSVAPF can be issued in primary or AR mode.
  12. For CSVAPF with the ADD, DELETE, and DYNFORMAT requests, PASN = HASN = SASN. For CSVAPF with the QUERY, QUERYFORMAT, and LIST requests, any PASN, any HASN, any SASN.
  13. For a QUERY or a CALL request with FASTPATH=YES, CSVDYNEX can be issued only in primary mode. For all other requests, CSVDYNEX can be issued in primary or AR mode.
  14. For CSVDYNEX CALL, RECOVER, and QUERY requests, any PASN, any HASN, any SASN. For all other requests, PASN=HASN=SASN.
  15. When the caller of the IAZXJSAB macro specifies the ASCB parameter, any PASN, any HASN, any SASN; otherwise, PASN=HASN is required.
  16. The 64 bit entry names are as follows:
    • ISGLCR64
    • ISGLID64
    • ISGLOB64
    • ISGLRE64
    • ISGLPB64
    • ISGLPR64
