In Rexx, not CLIST, I use BPXWDYN to allocate individual data sets for
each of my library concatenations, using RTDDN() for each catenand
except the first, and ignoring any failures.  Then I use BPXWDYN( 'concat ...')
to concatenate the successes.  Sporadically, I examine messages and resolve
the failures.

It works to include UNIX directories in SYSEXEC, except as the first catenand,
although IBM tells me it's not supported.

It's a PIT{A|Y} that CONCAT requires at least two operands -- I must count
and bypass when there's only one.  That effort should be done by CONCAT,
not abdicated to the caller.  Bad boundary condition design.
