How to suppress pup up window if an error occurs.

[mickey]

I'm running program unattended in background and would like it to simply quit, without presenting pop up if error occurs, which request user to choose abort.

Use ErrorBlock() and in your assigned function write the error message to a file for later review (and quit there, if requested).

See further details and example in the FlagShip manual FUN.ErrorBlock() and OBJ.Error class
