Does anyone out there know how to trap the return-key when the user hits the RETURN key in a field ??? I know that there is no message sent to the field script if the field property is not set to lock text. If I want to treat each line on the scrolled field as individual line, I need to limit the number of characters in each line and prohibit the entry of a RETURN key. Thanks in advance.

The following code in your field script will work: on returnInField --your code here end returnInField You must be using HC 1.2.1 or higher for this to work. See the release notes on this version of HC for more info. -Joe Melvin jm7f@andrew.cmu.edu

I got it from BCS, so if you can't find it, send me a note and I'll forward it to you.
