Thanks.
Well, they's concatenations, and they's concatenations, and it appears that
some concatenations is more equal than others. By a brief experiment:
allocate dd(ddn) dsn(dsn1,dsn2)
free ddn
... frees both catenand data sets. But:
allocate dd(ddn) dsn(dsn1)
allocate dd(ddn2) dsn(dsn2)
concat ddlist(ddn,ddn2)
free ddn
...frees dsn1 but leaves dsn2 allocated. So, I'm left wondering what's
different
between the control block structures created by the two processes. (Or did
I make an observational error?)
Unfortunately, the first form isn't available for concatenating:
o UNIX files
o uncatalogued data sets occupying different volumes.
