Delete if you like.
You need an RPG program to read the records and delete those you don’t want.
Open it with the U/update code use DELETE command
Or use the SQL delete …

But I’m too thick for your discussion
Why use DSPLNK and not use it to get a current picuture of all the .txt files in you’re directory?

I will explain it clearly.Assume the prog starts running today.So the purge file will not have details initially.Now as the program runs each day dsplnk and cpysplf will load details of text file to this purge file.These details should remain in the purge file until it is deleted after 2 months.So if a clear of th purge file is done befroe that wont that be a problem?Please let me know if am clear

I’m not sure I understand
You’re running DSPLNK each day?
You’re running DSPLNK with default object = ‘*’
You’re running DSPLNK with Output = *PRINT
You’re using CPYSPLF with defaults
TOMBR *FIRST
MBROPT *REPLACE
to copy this result into a flat file

Then you’re scanning the flat file to find txt files to delete.

The next time you run DSPLNK it will clean up the flat file.
If you want it cleaned up at the end of the job – repeat the steps
DSPLNK
CPYSPLF
At that time you will only get a list the existing txt files.

I dont think this would help…As of now my prog does the following create a txt file on a daily basis and also check for files older than 2 months for purging.If i do a CLRPFM or replace dont you think it will be a problem because it will not have details of older files.
that is if i run today a file abc20090110 will be created.the details of this should exist in the purge file for it to get deleted after a period of 2 months.
