Frank,

Thanks for your response. I will save the link.

I have more information than I had earlier. A colleague was trying to
read a VB large block tape data set, and it was failing. Their comment
to me was that LBI did not work with DF/SORT. When I couldn't find
anything (due to the difference in keywords), I posted the question.
What they meant by "didn't work" and what I interpreted it to mean were
two different things. In my mind, I guess, it would not have occurred to
me the DF/SORT would have an error in the code (it is rock-solid, thank
you), so I thought he meant it was not supported. He has since opened an
incident with IBM support.

So apparently, there is officially support for tape VB LBI for SORTIN
data sets, just at the moment it has a flaw in it.

IEBGENER appears to be able to read the tape without a problem, but
curiously, not IDCAMS.

We refer to it by the function name of "Larger Tape Block Sizes", rather
than "LBI" which is the interface name (that is, the way the support is
provided).  Just kind of an "external" vs "internal" thing.

BTW, if you're ever curious about what was supported in DFSORT when, you
can find out by checking the pdf at:
