No ignorance there, Pat.

If you wrote a program that only worked with a given blocksize, then
short blocks becomes a problem.  Even then, you still have to write the
program to work with a short block because the last block may not be
full.

My ignorance will now show.  How do you get short blocks into an IPCS
file?

I'm probably way out of date, but I thought IPCS required no short
blocks
within the data.  I assume there are still programs using BDAMish READ
processing rather than QSAM GET processing - processing physical blocks
rather than logical records.  Those programs can certainly be written to
handle short blocks, but it's up to the program.  The access method
won't
do it.

Have I shown my ignorance again? :-)
