The legacy formats don't support any of the new stuff; you need GOFF and program objects.

Are you saying OMF doesn't support VD references? Note that I don't need long external names, so I don't need GOFF for that. But if VD is only supported for GOFF, that might be an explanation as for why I didn't see it in the manual. I had previously assumed it was there, but I was just failing to find it. There are references to the CSECT being RMODE 64, so some level of 64-bit has presumably been added to OMF. BFN.
