The command line

The prompt given when the program is in command mode is the double arrow >>. The allowable responses are:

• A SPECX command (defined below)
• A VMS command preceded by a $ character.
• A script file name, preceded by an `@' character.
• A comment, preceded by a `!' or `*' character (most useful inside script files).
• CTRL(C) (here represented as ^C) to exit the program immediately.
