ISRFIND is 800+ lines of horribly-written IBM-style code, whereas FIND_ORIGIN is <60 lines of DougNadel-style code -- no more understandable, but there's lots less of it.
ISRFIND is a panel-oriented application requiring the user to be in ISPF whereas FIND_ORIGIN is an API that returns the precise dataset name in a usable format even in the absence of ISPF.
Code:
say "Running from" FIND_ORIGIN()
