Hi there,

I have a scenario here that is a bit complicated.

How can I retrieve the contents of a file and assign it as a variable value?

Say I have file AAA containing value "01", I would like to assign it to a SET command as...
Code:
//   SET   VAR=01

Pls take note that the file AAA's content changes all the time, it could be any number. Any ideas?

Thanks for your reply, but the file is not a PDS. It's a sequential dataset.
I can't use PROCLIB JCLLIB ORDER for this.

Any ideas?

The symbolic substitution in JCL is completed before the job starts.

read your file and retrieve the data
read the jcl and assign the data into the correct place in your jcl
write the jcl out to the internal reader

This has been discussed many times
A search on internal reader should give you an idea
