Rebuilding V8.2 BPCS Literal (message) Database

[Arnie Flangehead <arnie.flangehead@xxxxxxxxx>]

Hi All

In V8.2 BPCS there's a utility to maintain literals (e.g. the headings
on display screens), which underneath the covers is using *MSGF
SSAZ03, but it also has its own files built over the message file to
enable advanced features like search and replace, etc.

If you maintain a message using this utility your changes will be
immediately visible, but if you update SSAZ03 directly, the changes
will not appear in the utility till the database is rebuilt.

I want to update messages in a batch process using the CHGMSGD, but I
don't want to confuse other users/developers who might try to access
them via the BPCS utility. Therefore I want to also run the database
update in batch. The program appears to be SYS709[C], but I don't know
what the parameters are (I've tried with the obvious library, file and
vice versa). The programs are shipped without source and have no
observability data included so cannot be viewed or debugged.

Has anyone faced and solved this problem, or have a way to figure out
the parameters?
