Going even further, I have a separate form that displays "complete" information about the R:Base environment (connected database, user name, DEBUG, TRACE, ECHO, MESSAGES, ERROR MESSAGES, etc). The labels that display the on/off status of on/off settings are clickable and will switch the setting from on to off. I sometimes make the form available from the main menu as an "About" form. I can direct a user who's having a problem to check that form for various information I need, and I can have them set MESSAGES and ERROR MESSAGES on from there, then re-run the problem routine and report the error message back to me. Of course, if you didn't want this information exposed to the user you could make the access to the form hidden, as described by Bill. -- Larry
