We used to share a CA-TMS TMC between VM and MVS. VM:Tape had read/write access and users had read only access to the TMC file. We had a VM/CMS program that could read the TMC volume/dataset records and display the information using XMENU. The TMC contained control records at the beginning of the file with block offsets for the volser ranges that were defined. The LRECL and BLKSIZE of the TMC were used to calculate the number of blocks per track based on the device type, (was 3380, then later 3390). The user entered the volser of the tape they wanted to display and the TTR of the block/record was calculated, (based on the above info), and supplied to POINT, then a READ was issued to get the correct block/record.
TMS was replaced with RMM, which of course does not have support for VM/CMS and to make it worse, RMM uses a VSAM file, which cannot even be read currently on VM/CMS. I created a QSAM extract file from RMM and a QSAM "Index" file, (that contained the tape volser and record number in the extract file), so the "Index" could be read from VM/CMS to calculate the TTR to use with the extract file. The extract and "Index" file are updated every 30 minutes so the data is not "live" like it was with the TMC. It's a kludge, but what else can you do when IBM doesn't support their operating systems equally and they don't understand the concept of sharing data between different systems. -- Dale R.
