%ADDR() in a DS is not resolving to the correct value.

OS version is 7.2.

I've a program that uses a registered condition handler that is a *SRVPGM.

There is a copybook that contains the data structures, prototypes and other variables that define the interaction between the failing program and the condition handler using IBM's CEEHDLR API.

Among the DS's is the PSDS and the Communication Area used for the condition handler. This was all developed according to IBM's examples many years ago.

The Communication Areas DS contains a pointer to the failing program's PSDS. It is defined as follows:

* Communication area *
*---------------------------------------------------------------
D CommArea DS NOOPT
D CA_pPsds * INZ(%ADDR(PGM_PSDS))

The DS to pass control to the registered handler includes the above DS:

* CEEHDLR Interface *
*------------------------------------------------------
D CEEHDLR PR
D pConHdlr * PROCPTR
D CommArea * CONST
D Feedback 12A OPTIONS(*OMIT)

The problems are that when the program is initialized, the pointer is supposed to have a value, it does not.

When the %addr() is obtained in the c-specs, it finds the correct address for the PSDS.

eval CA_pPsds = %ADDR(PGM_PSDS);

The impact is that as the condition handler accepts control from the failing program, the address is invalid and the condition handler cannot resolve the address, so it fails.

When the address is forced in the c-spec, all works as expected.

I don't think that the *SRVPGM angle has anything to do with the error as my tame test program works just fine.

Anyone got any ideas? Barbara? :)
