As mentioned previously, the other environmental factors to be
concerned about in a recovery environment are:
- Authorization: problem state or supervisor state, PSW key, and
PKM
- SDWA storage key
- Dispatchable unit mode
- AMODE
- ASC mode
- Interrupt status
- DU-AL
- Program mask
- Condition of the linkage stack
These environmental factors differ depending on whether you are
dealing with the recovery routine or the retry routine.
