I had the same problem with Batch LSR's use of BLDVRP back in 1989. So in Batch LSR, we hand build the whole BLDVRP parm list using the IDABLPRM mapping macro. But IDABLPRM is not made available in either SYS1.MACLIB or SYS1.MODGEN. Batch LSR is part of the MVS BCP, so it can use VSAM's private macro (although I would have much preferred a BLDVRP macro which accepted variable parameters). I whined about this to VSAM development, but an agreement that Batch LSR could use IDABLPRM was all I got. Of course, you can submit a requirement to VSAM to provide a usable BLDVRP, or provide IDABLPRM. In the mean time, about all you can do is look at the expansion of BLDVRP and create your own mapping of the parm list (which is what the Batch LSR prototype code I inherited had done, much to my dismay).
