Tom, IIRC, a lot of the problems moving from static partitions to dynamic partitions arise from programs directly accessing certain internal control blocks, rather than moving to the more modern (and supported) GETFLD/MODFLD interfaces. VIDEO/370 is likely using an unsupported interface to access the LUB table. John P.

For those older folks out there, it is Video/370....Yep, still in use. I know the differences in JCL (hard assgns for UR isn't available for DYN). I have the same number of LUBS. I have the same partition size and default SIZE specified. I have the save LIBDEFs. I have the same partition JCL defined. But it fails when running in a dynamic partition with a rather bogus error message: I/O SECTION. PERFORM (EXTRACT) TO (OUTFILE) DEVADDR (SYS012) ****** CARD IN ERROR ****** TO (OUTFILE) DEVADDR (SYS012) SYS012 is assigned to a tape drive. (runs fine in BG and F9, gives error message when in dynamic). I would assume that Video/370 was written in Assembler, in days way gone by. So was there something, that an old program would use, that wouldn't be available in a dynamic partition? We are just going to run it in BG, no big deal. But I'm more interested in adding to my knowledge on something that won't run in a dynamic partition. Thanks Tom Duerbusch THD Consulting
