Summary of environment on entry to an ESTAE-type recovery routine and its retry routine

Table 1 summarizes some of the environmental factors for ESTAE-type recovery routines under different conditions. Specifically, the table lists the status information of:

The caller at the time of issuing the macro
The recovery routine at entry
The retry routine at entry.

Table 1. Environments of ESTAE-type Recovery Routines and their Retry Routines
Type of Recovery	When macro was issued	At entry to recovery routine	At entry to retry routine
ESTAE	ASC mode=primary	ASC mode=primary Linkage stack at time of error (see Note 1) PKM at time macro was issued	ASC mode=primary Linkage stack at time macro was issued (see Note 2) PKM at time macro was issued
ESTAEX or IEAARR	ASC mode=primary or AR	ASC mode at time macro was issued Linkage stack at time of error (see Note 1) PKM at time macro was issued	ASC mode at time macro was issued Linkage stack at time macro was issued (see Note 2) PKM at time macro was issued
ESTAI (through ATTACHX)	ASC mode=primary or AR	ASC mode at time macro was issued Linkage stack at time of error (see Note 1) PKM at time macro was issued For possible environment restrictions, see Restricted environments.	ASC mode at time macro was issued Linkage stack at time the retry RB was entered (see Note 2)

Note:

The linkage stack presented to the recovery routine might have additional entries, beyond what was the current entry at the time of the error, if a previous recovery routine added entries through a PC or BAKR instruction and did not remove them.
The linkage stack presented to the retry routine might have additional entries, beyond what was current at the time that the routine was activated, when the recovery routine set the SDWALSLV field.
At time of entry to the recovery routine, the AMODE will be the same as the time of invocation, except for ESTAEX and IEAARR routines. ESTAEX and IEAARR routines that were established in AMODE 64 receive control in AMODE 64; otherwise, ESTAEX 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 the PSW key that existed at the time it was defined.
