Abend error recording in the logrec data set

The system diagnostic work area (SDWA) is passed among the various levels of system and user recovery (STAE, ESTAE, and FRR) routines. It is used to pass information among the recovery routines and to collect and record information about the environment in which the error occurred. The O/C/EOV recovery routines put the following information in the SDWA:

The CSECT name of the O/C/EOV routine that encountered the error will be moved into the SDWAMODN field.
The CSECT name of the O/C/EOV routine that encountered the error will also be moved into the SDWACSCT field.
The CSECT name of the O/C/EOV recovery routine handling the error will be moved into the SDWAREXN field.
The O/C/EOV recovery routine moves the O/C/EOV recovery routine parameter list (RRPLIST) into the variable area of the SDWA. The contents of the list is shown in Table 1.
