actually process the data set through OPEN. While it is dangerous ...
Dangerous? (*) Sensitive to OS changes, maybe, but as long as
*all* the necessary precautions are taken, why is this dangerous?
That said, bypassing OPEN requires a lot more effort than
should be necessary to obviate update of the last referenced datestamp.
(*) I used to work with a guy who prided himself on
being "clever" enough to program around any restrictions
imposed by the OS that got in his way. Of course,
this always involved APF, Key0, etc. Yet, anything "clever"
that anyone else did, even though it was using available,
unauthorized, standard facilities, was branded "dangerous" by him.
Whose code was more reliable? Certainly not his!

Steve,
Too late - check out IHAUDA in SYS1.MODGEN.
Cheers,
Greg
