I want to change an string in a series of JCL's. For example change
"DSN=IMS.PRJ01.OLP01" to "DUMMY"
Cause of many JCL's must be have "DUMMY" instead of "DSN=IMS.PRJ01.OLP01", it's difficult and time consuming to do this changes one by ony in JCL source. Is there a utility to do this by a batch job? And what is this form and syntax?
