The beginning of the thread was my comment that Fileman was WRITEing (not READing) comments about social security numbers during an apparent input transform.
But no one has been able to tell me where the message is stored. Is it in the data dictionary? Is it in a *.m file (stored separately from the database on GT.M). Or does it matter? I realize that we have been generalizing the situation. But it seems that we are talking about hypothetical concerns without looking at specific instances of the situation.

I do not know if it was even discussed. ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc. Do you grep through log files for problems? Stop!
