AFAIK there has been no change in the way QSAM enerates short blocks
with FB. The occur when:

 1. You close the file with a partially billed buffer.

 2. You issue a TRUNC.

Note that in the first case, if you subsequently open the file with
MOD, QSAM will not read and rewrite the short block; it starts a new
block over the EOF.
