a variety of reasons, a system may have multiple source
versions of a compiled program object. Determining which
of these versions matches the program can be an extremely
difficult task. If a source has a last change date and
time exactly matching the program's "source file change
date and time," then a match is almost certain. Otherwise,
it can only be achieved through compilation and then exhaustive

relative problems follow:
a source and then comparing the size of the program
it generates to the original program size leaves two
problems. First, program sizes may not match even
if the source is correct because of changes to the
compiler from release to release. Second, even if
the programs do match in size, changes could have
been made which do not affect size (e.g. ADD TAXTOT
TOTNET and SUB TAXTOT TOTNET generate the same amount
of machine code).
the latest source that has been changed also is very
risky. That version might have been a very old one,
but was simply changed by the addition of a comment,
which would update the change date and time.
is a programmer's utility designed to resolve the problem
of matching a program to the copy of the source which
produced it. The utility combines features of two of JuggerSoft's
other licensable utilities: SourceMatch,
which locates all copies of sources whose name matches
that of the programs on a systemwide basis, and the JGSTM
RPG Decompiler, which translates machine code
back into source.
