Hi all,

I'm using the following compile JCL to compile two programs (FDUAA & FAAAA).

//CMPLINKJ EXEC YOPTCLNK
//COMP.SYSLIB DD DSN=MACRO.PRODY2K,DISP=SHR
// DD DSN=MACRO.TRANY2K,DISP=SHR
// DD DSN=MACRO.TESTY2K,DISP=SHR
//COMP.SYSIN DD DSN=MSN.PL1.SOURCE(*),DISP=SHR << *FAAAA or FDUAA
//LINK.SYSLMOD DD DSN=MSN.COMPL.PL1.LOAD,DISP=SHR
//LINK.SYSIN DD *
NAME FAABK(R)
/*

But wen i look at the load i could see that
the load of FDUAA is generated with AMODE = 24, RMODE = 24
but
the load of FAAAA is generated with AMODE = 31, RMODE = ANY.

Both are almost similar programs.

Can anyone please explain this behaviour.

Thanks in advance
Nirmal.

does one have dataset use and the other not?

no...

FAAAA program reads 2 datasets in main program and 2 data sets in a called module.
FDUAA program reads 3 datasets in main program and 2 data sets in a called module.

Unless you tell it differently, the Binder uses the AMODE and RMODE of the input modules (including any modules brought in from SYSLIB) to establish the AMODE and RMODE of the load module it creates. Now I'm not very familiar with the more recent PL/I releases, but the source code may have a mechanism to specify the AMODE and RMODE. This is what you should be investigating.
