Yea....I recall that. It is on our list to replace it. One of the nice features was that it would do some basic field validation against out Total DB. Now that we are in the 7th year of our 3 year migration plan to DB2/VSE, we are not going to replace Video/370, until the application get on DB2/VSE. Then the PC based application can still do validation via remote SQL calls. And Video/370 will be the last of our macro level code. And we can completely get off of CICS/VS. And it isn't important enough to look for the optional source <G>. Tom Duerbusch THD Consulting >>> "John P.

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
