Summary of environment on entry to an ESTAE-type recovery routine and its retry routine
- The caller at the time of issuing the macro
- The recovery routine at entry
- The retry routine at entry.
| Type of Recovery | When macro was issued | At entry to recovery routine | At entry to retry routine |
|---|---|---|---|
| ESTAE | ASC mode=primary PASN=HASN=SASN |
ASC mode=primary PASN=HASN=SASN Linkage stack at time of error (see Note 1) EAX at time macro was issued PKM at time macro was issued |
ASC mode=primary PASN=HASN=SASN Linkage stack at time macro was issued (see Note 2) EAX at time macro was issued PKM at time macro was issued |
| ESTAEX or IEAARR | ASC mode=primary or AR PASN=HASN=SASN or any PASN, any SASN, any HASN |
ASC mode at time macro was issued PASN and SASN at time macro was issued Linkage stack at time of error (see Note 1) EAX at time macro was issued PKM at time macro was issued |
ASC mode at time macro was issued PASN and SASN at time macro was issued Linkage stack at time macro was issued (see Note 2) EAX at time macro was issued PKM at time macro was issued |
| ARR | N/A | ASC mode at time stacking PC routine
was entered PASN and SASN at time stacking PC routine was entered Linkable stack at time of error (see Note 1) EAX at time stacking PC routine was entered PKM at time stacking PC routine was entered |
ASC mode at time stacking PC routine
was entered PASN and SASN at time stacking PC routine was entered Linkage stack at time stacking PC routine was entered (see Note 2) EAX at time stacking PC routine was entered PKM at time stacking PC routine was entered |
| FESTAE | ASC mode=primary PASN=HASN=SASN |
ASC mode=primary PASN=HASN=SASN Linkage stack at time of error (see Note 1) EAX at time SVC routine was entered PKM at time of error |
ASC mode=primary PASN=HASN=SASN Linkage stack at time SVC routine was entered EAX at time SVC routine was entered PKM at time of error |
| ESTAI (through ATTACHX) | ASC mode=primary or AR PASN=HASN=SASN |
ASC mode at time macro was issued PASN=HASN=SASN Linkage stack at time of error (see Note 1) EAX at time macro the selected retry RB was entered (see Note 2) EAX at time the macro was issued PKM at time macro was issued For possible environment restrictions, see Restricted environments |
ASC mode at time macro was issued PASN=HASN=SASN Linkage stack at time the selected retry RB was entered (see Note 2) EAX at time the selected retry RBG was entered |
- If a previous recovery routine added entries through a PC or BAKR instruction and did not remove them, the linkage stack presented to the recovery routine might have additional entries beyond what was the current entry at the time of the error.
- When the recovery routine set the SDWALSLV field, the linkage stack presented to the retry routine might have additional entries beyond what was current at the time the recovery routine was activated.
- At time of entry to the recovery routine, the AMODE is the same as the time of invocation, except for ESTAEX, ARR, and IEAARR routines. ESTAEX and IEAARR routines that were established in AMODE 64 receive control in AMODE 64, otherwise ESTAEX, ARR, and IEAARR routines always receive control in AMODE 31.
- The AMODE at the retry point is the same as the AMODE on entry to the recovery routine, unless the SETRP RETRYAMODE= parameter specifies a specific retry AMODE.
- An ESTAE-type recovery routine is entered with PSW key 0 whenever it was defined with a PSW key less than 8. Otherwise, it is entered with the PSW key that existed at the time it was defined.
- The AX for the recovery routine or the retry routine is always the AX for the current PASN of the recovery routine or the retry routine, respectively. The system does not modify the AX value during recovery processing.
