Nothing comes to mind. You could kind of kludge it from DSPTAP to an outfile (there's an API equivalent); I think you'll only need *LABELS. You'll have to build a lookup table of some kind to determine theoretical tape capacity from the density code. Hopefully there's enough to be able to tell the individual file sizes; might have to calculate from block size and number of blocks.

Try it interactively to see what all is there. Interactive DSPTAP goes one label (file) at a time, so you don't have to read the entire tape.

One thing that may complicate this, even if it all looks good, is how compression figures into it. The sizes you get from the VOL2 labels will be after compression (what's actually on the tape). You may need to go to *SAVRST to get the sizes of what was saved, though it might be close enough if you just look at what's on the system now.

Couldn't find anything good enough to use, so I just saved what I could and waited for the Mount Next Tape message. Fortunately I didn't get it.

I did add up the block size x blocks saved and did some rough calcs using those figures--I'm saving about 1.2GB on a tape designed for up to 2.5GB so I think I'm good for now.

Thanks, Dale.
