I am reviewing other person's code. He used a self-defined function. How can I get this functions's detailed information, for example, the funciton's code? Thanks
Check the code, if it's defined within the program. Otherwise you're going to have access to the same catalogs or wherever they stored the code for said function.
Look for a PROC FCMP in the code.
The function has been stored. How can i open the stored function, or to show its content in log.
You can also ask proc fcmp to print the code:
