I have a requirement to search multiple strings in a list of copybook pds and from that result I need to identify the programs using that copybook from source lib and write in a file as report. I created the JCL but it is taking lot of time and abending with S322. So I tried using a rexx program. I created for searching one single string search. How can I try for multiple strings? Also can we pass the search strings in a dataset to rexx as input so that it gives result based on that?
