Ah!!  By 'not allowed' I meant that it was not using my record change -- but
I was using EXECSTAT = 1 as well!

I missed the EXECSTAT = 2 ...  I only had 0 (fail) and 1 (write) as valid
choices -- I missed the "2".

Let me try my code with a "2" and see -- that's likely my whole issue ... 

Thanks Jeff!

I'm not sure I understand "not allowed" - are you getting an errors?

That's the whole point of EXECSTAT:

0 = don't write the record
1 = write record as passed in, ignoring any changes made in trigger
2 = write record as edited by trigger

This example will overwrite field 1:

SUBROUTINE MY_TRIGGER_SUB(X.EXECSTAT,X.DICT,X.FILE,X.ID,X.REC)
X.EXECSTAT=2
X.REC<1> = 'Happily overwriting fields in this record'
RETURN

I use this for stored computed columns and other things that sound 
similar to what you want.  Here's a real example that sets a slew of 
default values anytime a record is written:

SUBROUTINE H08.T.H08.JA.SEARCH(X.EXECSTAT,X.DICT,X.FILE,X.ID,X.REC)
X.EXECSTAT=2
IF X.DICT = '' THEN
* record changed who/date/time
   X.REC<5> =UPCASE(@LOGNAME)
   X.REC<3> =DATE()
   X.REC<4> =TIME()
   IF X.REC<17> ="" THEN
* record added who/date/time
     X.REC<17> =X.REC<5>
     X.REC<1> =X.REC<3>
     X.REC<2> =X.REC<4>
   END
* Default values...
* Next Question=1
   IF X.REC<25> = '' THEN
     X.REC<25> = 1
   END
* Num apps
   IF X.REC<46> = '' THEN
     X.REC<46> = 0
   END
* Status=Search Creation
   IF X.REC<10> = '' THEN
     X.REC<10> = 'SC'
     X.REC<11> = DATE()
   END
* Accept Resumes=NO
   IF X.REC<20> = '' THEN
     X.REC<20> = 'N'
   END
* Cull method=view all apps
   IF X.REC<23> = '' THEN
     X.REC<23> = 'A'
   END
END
RETURN
