I assume you are looking for a set of files, the names of which are not
predictable.

I suggest you execute a LISTF on the same fileset, perhaps directing the output
to $NULL if you do not want to see the listing.

 :ERRCLEAR          <To set certain predefined variables, including CIERROR,  to
default>
:LISTF fileset>$NULL
:IF CIERROR <> 431 THEN
:    LISTF fileset >*MyMsg
:ELSE
:               do something if no files exist
:ENDIF

 Subject: [HP3000-L] LISTFILE ,6 Question








To All,

I am looking for a "clean" solution to the following problem.  It must be in
MPE/iX JCL.  Please, no 3rd party software solutions.

I am using ListFile ,6 >*MyMsg to create a list of files to process.  This works
great, except when there aren't any files in the target directory that match my
selection.  Then I get two records in my msg file telling me the ListFile
command and the fact that there aren't any files found.  This is a pain to test
for (using cierror 920).

Is there a ListFile option that will only display the file names selected, and
provide an empty file when none of the files matches the selection?  This would
make scripting much easier.  (Don't you just hate it when commands do things
other than what the documentation says they do!!!!!?)

Thanks for any help.

Ric
