I was looking at an assembler program today that (accidentally) passes a
null parameter to our common VSAM I/O routine as the target work area for a
GET request.
The common routine uses a set of predefined ACBs and RPLs, and does a MODCB
RPL to point to the caller's work area when a GET is requested. I'd have
thought there'd be a S0C4 or a VSAM error when the GET is issued, but
apparently this is not the case.
I don't see anything specific in the DFSMS manuals regarding the AREA=
operand on the RPL, so I assume VSAM simply decides it isn't present and
ignores it.
Opinions? Comments?
