If we just know the load lib of the program, How can one find the source (the location from where the source code of the program was compiled) code.
Also is there any way to search in 3.14 option a variable in the data set '*.*.*'. I mean to search all PDSs all at once.
There are few ways to invoke SUPERC for search. Starting on z/os 1.4 (I think), they introduced a new 3.4 (DSLIST) command. The command is SRCHFOR, and you can read more about it in the fine manual. I believe you can achieve what you want with this command, although I don't understand the logic behind it.
