Hello,
These were recently posted in this thread (about things that can go thud
when a dataset is allocated but not used).
"For SMS-managed datasets, this phenomenon goes away as SMS writes an EOF on
the first track on the new dataset."
and
"If you did have this under SMS management, you
wouldn't have the problem. When the system allocates a PS
dataset on SMS dasd, it immediately writes an EOF. You can
see recent threads for details on exactly when this does
and doesn't happen."
If a dataset is allocated under sms management via JCL/IEFBR14 will it
ALWAYS raise an end of file on the first read? A physical eof is written
even though the dataset was never referenced other than alloc/de-alloc? My
confusion is due to the last part of the preceeding quote "when this does
and doesn't happen".
Thanx,
d.sch.
