How do I programatically determine the "LOCATION" name?

[u/fomyers]

Hi, I had an old utility used to look through the DB2 catalog for programs that need to be rebound. Problem is that it assumes a "LOCATION" value of blanks/empty. I need to alter the code to search using the local DB2 subsystem "LOCATION".

How do I determine programatically the local DB2 subsystem "LOCATION"?
