I have a requirement : I have a file with the names of around 100 files. I have to manually check if the files are existing or not. Can someone help me to do this in Rexx ?

OK. Help us out a bit. How would you do this manually? What TSO/ISPF or REXX functions have you tried? What did or didn't work?

Hints:

LISTCAT is useful for this.

The REXX SYSDSN function is useful for this.

The TSO/E LISTDS command is useful for this.

The REXX LISTDSI function is useful for this.

Try inputting the file of DSNames into a LISTCAT, iterate for each DSN and check LISTCAT return code...
