It is a little tricky. In the Assembler Services Guide there is a section called Linkage Stack Considerations in chapter 8, the last paragraph of which says:
When you issue a PR, the system automatically deactivates all ESTAE-type recovery routines that were previously activated under that current linkage stack entry. What I was writing about was, being lazy and not wanting to allocate a save area, I used BAKR/PR to save and restore the registers when I called a subroutine to do some initialization including a setup of the ESTAE, and the ESTAE was not there when the program later abended. (I thought I knew everything and hadn't read the previous paragraph.) So, what happened was the system very nicely setup my ESTAE in the subroutine, and very nicely deactivated it when I exited the subroutine. Now, if I hadn't use BAKR/PR and done a real subroutine call, all would have been fine.

Then I saw a thread with Chris Blaicher where the upshot as that a BAKR would deactivate it I did a search on the archives but didn't come up with anything ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ________________________________ ATTENTION: ----- The information contained in this message (including any files transmitted with this message) may contain proprietary, trade secret or other confidential and/or legally privileged information.
