Required Entry

[Deskin, Bob]

If I understand this correctly, you'll be doing a retrieval and displaying
what you found. Some fields won't have a value. You ant to go through a
change or modify process such that the user must enter vaues in certain
fields.

This sounds like it must be done procedurally. If you want to automatically
go into the change process, I suggest using AUTOMODIFY or a PUSH MODIFY in
the POSTFIND if it has to be conditional. I wouldn't  suggest panel
processing so you may need to write your own MODIFY procedure. Within the
MODIFY you could conditionally prompt as required. To ensure the user enters
a value, you'd have to test the size of FIELDTEXT in the INPUT procedure.
The REQUIRED option only applies to entry of a new record. Since you only
want to force something if there's no value already there, you'll have to
test that as well, as in (for relational NULL columns)

IF item IS NULL and 0 = SIZE(FIELDTEXT)
  THEN ERROR "A value is required."

For nonNULL values, you could use any appropriate test such as testing for 0
or spaces. If you want to force an edit of the existing value even if the
user enters nothing, do the following

ACCEPT field
IF NOT PROMPTOK 
  THEN EDIT field
