set showmsgnum= { on | off}

If this option is set to on (the default), then error and informational messages displayed in the status line and various dialog boxes are prefixed with a unique message number on the form [Annnnn]. If set to off, then message numbers are not displayed.

This message number may be needed by Arbortext Technical Product Support when reporting error situations, particularly when error messages have been customized at your site to display non-standard messages.
