I've got a requirement to determine whether a DD is allocated DUMMY. I know how to find the TIOT, get the JFCB with SWAREQ, check for 'NULLFILE' and loop through all of the JFCB chain. Is there any easier way? That's a lot of complexity for a simple question!
Why? I'm trying to avoid an S013-64 on a BPAM file if the user does not supply a DSN to a PROC. I'm defaulting the DSN to NULLFILE. I'd like to be able to determine that from my program. The program is in IBM C but I can readily call out to assembler. The OPEN for the BPAM DCB is in assembler, not using the C library. Thanks!
