RE: errmsgid keyword--unexpected results

I saw that one.  I wondered about it since the build the subfile routine
starts with a write to the subfile control record to clear the subfile, but
the thing that fooled me was that when doing the same thing for the other
search argument, the error message behaved the way I thought it should.  

When I started on the 400, I was taught to avoid putovr and its friends--the
rationale being that we had at least a 56K data stream everywhere and didn't
need to economize and deal with the additional complexity.  Looks like I
should have learned something about it anyway.  One of my coworkers asked me
"Are you using putovr?"  I thought I wasn't.  <g>

I think earlier (as in S/38) documentation explained the relationship 
between ERRMSG, ERRMSGID, PUTOVR, etc. but I've known it for at least 12 
years.  The only reference I could find which hints at your problem is the 
following quote from the Restrictions and Notes section of the DDS manual 
under ERRMSG and ERRMSGID.

"For input or output capable fields, ERRMSG and ERRMSGID are in effect only 
if the record containing the field for which they are specified is already 
on the display."

Section 2.7.1.1 of the Application Display Programming manual also describes

this behaviour.

Simon Coulter.
