I feel otherwise.
o Won't ISPF Edit under Vista perform the hunt for you?
o The value appears in the assembler listing.

I once was tasked with modifying some open-source IBM code
(actually PL/S compiler output). There I found:
FIFTYSIX EQU 56
... the best/worst of both practices.
And every line had a line comment, often inane. I found it
evidence of mindless enforcement of coding standards.
And at some point, an analogue of:
LA R7,Token_Len LOAD 5 in GR7
But I needed to change Token_Len, then hunt for the invalidated
line comments. (I deleted them.)
