You can show a message and have your "over limit" field display, but you can't 
use ERRMSGID() as part of it.

>From the DDS manual:

"When an ERRMSG or ERRMSGID keyword is in effect, no processing other than the 
processing for these keywords is performed for the record. If neither keyword 
is in effect, the record is processed in the normal manner."

The only thing signalled/sent back to the display is the ERRMSG itself plus the 
5250 error signal which can do some cursor positioning, etc. AFAIK, no data 
goes to the display. The screen data will be unchanged.

If you want a 'message', you'll have to send the message as data to the message 
line and not use an ERRMSG feature. Of course, you'll lose any automatic 
attribute/cursor changes and have to control those yourself.
