So looks like you have to specify the SYSSTATE macro in z/os 2.4.

Thanks Joe!
I have the feeling that has changed for v2.4?
The code (which worked fine on z/OS 2.3) had this comment:
* NB: The SDWAPARM field points to an 8-byte area, when *
* ESTAEX is issued "in AMODE 64" this is the 64-bit *
* address passed in the PARAM field of the ESTAEX *
* invocation. But "in AMODE 64" is a mis-nomer; *
* this is only true if SYSSTATE AMODE=64 is specified*
* when ESTAE is invoked. When that is _not_ true, *
* this field contains a 4-byte address and a 4-byte *
* ALET (as it does for a regular 31-bit assembly.) *
* However, the exit is still given control in AMODE *
* 64 if ESTAEX was invoked in AMODE 64. *
So - there was clearly some confusion at some point in the past...
And - the way we had solved it was to not specify SYSSTATE AMODE=64
and to let things go with the 32-bit mode SDWAPARM... but - at least
empirically, the ESTAE EXIT was still driven in 64-bit mode.
(But - since we didn't know the AMODE of the ESTAEX, we had to handle
the EXIT running in 31-bit or 64-bit anyway.)
So - perhaps the "fix" for now is to just drop to AMODE=31 to issue the
ESTAEX
and let the ESTAE EXIT get entered in AMODE=31 and go with that... I hope,
if the current AMODE at the time of the exception is 64-bit we still get all
the 64-bit info... we'll see...
Or - I suppose - we could test the AMODE at the point where the ESTAEX is
to be done, and have dual-paths (one assembled with SYSTATE=64 and one
without?)
I'll try and dig up the older doc to see what it says...
- Thanks again! -
