RE: Generate hash code for a source member?

WAY too slow.  Thousands of members to compare.  Also, I find CMPPFM
cumbersome to use when comparing many members and want only to know whether
they match or not.

Why don't you define a DDM file and do a 54 (compare) on the sources ? Too
Slow ?

Oggetto: Generate hash code for a source member?


(Cross posted on Midrange-L, RPG400-L, & MI400)

Has anyone invented this wheel?  I'm looking for a way to compare source
members on different systems to determine whether or not they are
identical - Yes or No.  If different, I don't care how different.

Because I don't really want to save & restore whole source files between two
systems, my thinking was to create a hash code for each source member based
on the contents.  Create a file with fields:  Library Name, File Name,
Source Member Name, Hash Code.  FTP the file from the system A to system B
and compare the two.  I'm fairly confident that the two source files are
identical, but I need to be sure.

Is a hash code generator what I'm looking for here?  Feed in
Library/File(Member) and get back a 16(?)-byte hash code?  If so, does
anyone have one that runs on V3R2?
