My question has to do with checking whether someone is fraudulently messing
about with data.
*********************************************

Given a field, say fieldString
I want to add a character
fieldString += invisibleCharacter;
I want to do that when data in any record is changed by the user
I don't want invisibleCharacter to display on the screen but I do want to
be able to check if invisibleCharacter is present in fieldString: what
character could invisibleCharacter be? (I need about four different
characters to indicate what has been changed.)

There is no spare room in the record to add a digit. Also the application is
up and running.

When you say "record", where exactly is this record being stored?
Rule #1 in Rob's data rulebook - NEVER use one peice of data to mean two
completely different things.
If you want an audit, checksum, or hash field, mysuggestion is create a
seperate field.

Hi Rob,

Thank you. That obviously makes total sense. I need
another field, which I cannot conjure up because the
application is running with data and I cannot change
the record lay-out any more. I will look for a different
solution.

Patrick.
