Hello Everyone!

There are some files in our environment that are created automatically each day by some REXX utility, these files are not GDG some of they are created by a variable (D&LYYMMDD) that puts the date at the end of the name of the file.

The files are created like this

SMF.LPAR.RACF.D200101
SMF.LPAR.RACF.D200102
SMF.LPAR.RACF.D200103
SMF.LPAR.RACF.D200104
SMF.LPAR.RACF.D200105
SMF.LPAR.RACF.D200106

This files always are created with the same 4 hlq (SMF.LPAR.RACF.DXXXXXX) the only thing that it chage are the numbers of the date

I'm creating a job that creates a report of RACF activity, but my inputs are those files. I want to schedule this job taking the last of those inputs.

Is there any way that I can do this? I'm guessing that I need to use some REXX program to do this.

Regards!!

Another way may be using PARSE statement in REXX

What scheduler do you use? Date variables can certainly be substituted by TWS, and most likely all others as well.
