"CLEAR PROGRAM main" will not work the way you have things arranged. If an error occurs in "main" or any routine called by main, your CLEAR PROGRAM statement will not work for "main" if issued within the error handler. You need to set a flag in the error handler, let the stack unwind, and then test for the flag and issue the CLEAR PROGRAM if the flag indicates that such an action is appropriate.
