When spanning is specified for blocked records, QSAM attempts to
fill all blocks. For unblocked records, a record larger than the
block size is split and written in two or more blocks. If your
program is not using the large block interface, each block
contains only one record or record segment. Thus, the block size
can be set to the best block size for a given device or
processing situation. It is not restricted by the maximum record
length of a data set. A record can, therefore, span several
blocks,
There's more for extended BDQ and BFTEK=A, but it's probably not
relevant here.
