It really helps if you do report things - the 15APR99 thing did
get fixed. 31DEC99 is always a full install - we do not give out
binaries.

I wanted the date on IMAGR.HLP not PRTCC.HLP. But the .exe date
above tells me that the help file (inputs) you sent does NOT match the
load module. This will cause the whole thing to mess up...

The mnj is run by you not us. You may have a cron job or may be doing
it by hand or ?? and all you need to do is fix the reference to
15APR99 to 31DEC99 to get it to work. But if you are messed up it
would be best to delete everything and start over. I attach the
current IMAGR help file (cutting it off after the inputs part) for
reference.
