Okay, I went back to the one set of code where this worked perfectly and found that the

#INCLUDE CONSTANTS.H

statement was not in the INIT of my form, but in the actual procedure within the form where it was needed right away. I assumed that if it were in the INIT that it would carry through in a GLOBAL manner on the form level, but that is not the case.

The #INCLUDE has to be placed precisely where it is needed, if in a form, then right in the procedure in the form where it is needed. Placing it in INIT event/procedure did not do the trick, since the

#DEFINE CRLF CHR(13) + CHR(10)

was to be used in a procedure within the form.
