Changing the JCL is my preferred method, but they would like an "easier" way.  
Also, D09182020 is 9 characters, so would cause a JCL error.  But I understand 
what you meant. :)

Mike designed REXX as a programming language. JCL is not and was never intended 
to be a programming language. This is something that should be handled in the 
environment that creates and submits the JCL.

I understand that system symbols are not supported in JCL DSNs because of
o ambiguity between EXECSYS and CNVTSYS
o queue latency -- the job might run at a time not matching the JCL symbols.

(If the actual date and time values are important I understand they
may be invalid because around midnight date and time might be
fetched on different days, resulting in a 23+ hour error.� Murphy
says this will only be a problem when it matters.� Rexx can do it
right; why can't JCL?)

Use the seconds also, as D200917.T112359.� With thousands of entries
a collision is likely.� And use YYMMDD for the date for easy sorting of
displays.

Is it possible to rename a tape data set?� That would seem to require
overwriting the HDR1 label, but tapes can't be updated in place.

I'm imagining a sequence such as:

Momentarily catalog HLQ.FICHE.TAPE

DEFINE ALIAS HLQ.FICHE.TAPE.D200917.T112359
��� SYMBOLICRELATE HLQ.FICHE.TAPE

Uncatalog HLQ.FICHE.TAPE.� I understand that symbolic aliases
remain when the RELATED name is uncatalogued.
