Start with:
3.1.3.2.2 "z/OS V1R7.0 DFSMS Using Data Sets"
3.1.3 Variable-Length Record Formats
3.1.3.1 Format-V Records
3.1.3.2 Spanned Format-VS Records (Sequential Access Method)
3.1.3.2.2 Segment Descriptor Word
What's your language of choice? If possible, override to RECFM=U
in the DD statement; read raw data; dump in hex and inspect.
Rexx won't read RECFM=U, so I'd use REPRO to convert to RECFM=V
and try to process that.
(just untested ideas)
In a similar case, I overrode to RECFM=U and used IEBGENER to copy to
an HFS file which I processed with Rexx SYSCALL read.
