Hi everybody,

I had an requirment that, i need to create REXX program to go and edit the PDS members(list of members inside the PDS library) in Mainframe and save the changes. Here one more thing is, I am going to replace the present string in the member with the new string at any line.But i don't know, the string which is present in the member and don't know the length of string too.

So i am planning to use EDIT MACRO to edit the members but i don't have an idea to replace the unknown string with the new known string.If you have any idea, please inform me. It will be very helpful for me..

Sounds like you need to pass the source and replacement strings as parameters to the Rexx Exec. Or, maybe you can read the strings in a file from the Rexx Exec.
