Error Checking

MSGMX tracks command-line input and alerts you at the first invalid term entered.

A command or argument is considered an error or invalid if:

  • the command, option, or flag is unknown
  • an entered option, argument, or flag cannot be used with the command or option it follows
  • the value specified is out of range or not of the appropriate type (e.g., numeric or alphabetic) for the option with which it is associated

If the syntax of the entered command-line entry is invalid, MSGMX prevents you from executing the command or option and displays an error message at the bottom of the command window above the status bar explaining why the entry is in error. The error will need to be corrected before you can press <ENTER> and execute the command.
