So "it also updates the change-logs in each of the affected execs"
statement is incorrect. They weren't 'affected execs'.
Why on earth are you updating change-logs with (in effect) "no change"
statements?
Why don't you stop inserting pointless change-log entries ... then you
won't have the 'compare' problem?
The input file for the affected execs does change, but the changes may not
affect all of the REXX execs/edit macros that are used to process its contents.
The "master" exec/edit macro (it's both) just extracts all the relevant data,
and passes it on to the various per-exec/edit macro subroutines. It has no clue
whether the data to be processed by any of these other exec/edit macros has
changed.
The, until yesterday, code would willy-nilly copy the new data, whether changed
or not, into the member, and update the change-log. What I wanted to do was to
just insert the data, do a "COMPARE *", and then either do a "cancel", if there
were no changes, or call a common subroutine to update the change-log.
Given that the "COMPARE" command doesn't seem to return its messages in the
designated variables, I have for now resorted to comparing every line of the
block-of-lines-to-be-replaced with its new version, and only when that tells me
that there are any changes I will replace the old lines with the new ones, and
update the change-log.
