Terry Prime shows a job snippet (snipped further here):

I believe Tad Bochan was right on the money, but I'd like to elaborate
a bit.

1. The :copy command is smart enough to put the target file in the same
   domain (perm or temp) as the source file.  Since DDFS is permanent,
   DDFS1 will be permanent as well.

   This means that DDFS1 really *does* exist as a permanent file.  Right?
   It's just that it's empty at EOJ because...

2. The :echo command assumes it is writing to a temp file unless BOTH of
   the following are true:

        a. something like :FILE DDFS1.SYSOPER,OLD is issued
   AND  b. the :file equation is referenced explicitly as Tad stated,
           e.g., :ECHO !DIR>*DDFS1.SYSOPER

3. Please please please do *something* to set off the :if statement.
   I may speak a heresy, but indenting the body of the :if is not the
   only technique here.

   If the block is relatively short, then certainly indenting is helpful.
   For a long :if block, you may want to use something like

        # ------------------------------------------------------------
        if hpday = 7


        statement 1
        statement 2
        ...
        statement n


        endif
        # ------------------------------------------------------------

   Of course, this works only to a point, but it's a thought.
