Grey area here. I would say that depends a great deal on the
experience and skill levels of the programmer. Not to mention the
final intended purpose. I've used QSAM to access individual members
of a PDS, in name sequence, but it's not a practice I'd recommend to
the novice.

It is not that hard. You read the directory (assuming it is a PDS and
not a PDSE [Which I am not sure will act like a PDS for reading the
directory]) one block at a time using BSAM. You then use OPENJ or
SVC99 to allocate the member and read it as a normal QSAM file [ie:
Read it as if you allocated it via a DD with DSN=DATASET(MEMBER)]. So
long as a member is allocated it is treated as a SEQ file by QSAM
(just make sure to open as INPUT - Using this method for PUTs is
asking for problems).
