DSAB+x'30' is the 4-byte subsystem name in EBCDIC.
DSAB+x'34' is the "SUB-SYSTEM COMMUNICATION AREA POINTER"

There's an "SSCM" documented in MVS Data Areas but I don't know if that's a
map of what DSAB+34 points to.

Subject: Information on parameter SUBSYS=

Hi, all.

 

I'm writting an assembler program and I would like to get some informations
that are specified on parameter SUBSYS=.

 

Example:

//A    EXEC   PGM=MYPROG

//DD1    DD    SUBSYS=(ABCD,EOSGRP10,0000,,,20090102,121110)

//DD2    DD    ..

 

I would like to get the values specified after the name of subsystem ABCD.
Where can I find this information searching z/os or others blocks?
