I think I've run into an interesting problem with ESTAEX
when it is invoked in AMODE 64 without SYSTATE AMODE=64
set at assembly time.
That is, this is code that could potentially run in either AMODE 31
or AMODE 64... so it's not assembled with SYSTATE AMODE=64.
Macro expansions can differ depending on the SYSSTATE settings. It's not
safe to ignore that.
If the module can legitimately run in either AMODE, I would do something
like:
| SYSSTATE PUSH Save current SYSSTATE
| TAM , Test addressing mode
| IF O If 64-bit mode
| SYSSTATE AMODE64=YES Tell macros how to expand
| ESTAEX ... Establish recovery exit
| ELSE , Else 31-bit mode
| SYSSTATE AMODE64=NO Tell macros how to expand
| ESTAEX ... Establish recovery exit
| ENDIF , EndIf
| SYSSTATE POP Restore current SYSSTATE
