PAUSE

        [SIC\]PAUSE "Message"

    Set a break point in a Loop or a Macro.  PAUSE returns  control to  user
    when  executed   in   a  macro.   The  prompt is changed to indicate the
    excution level.  Any valid command  can be executed while  in  interrupt
    mode.   The execution can be resumed by typing CONTINUE, aborted by QUIT
    (or RETURN, depending whether an error status is desired). NEXT may also
    be used for the Loop.

    If PAUSE is followed by an argument, this argument  is  typed  when  the
    pause  occurs. When typed in interactive, PAUSE generates a traceback of
    the levels of execution in SIC.

    A pause is generated after completion of the current command if you type
    <^C>  on  the  keyboard.  This  allows  you to interrupt any sequence of
    commands (even if ON ERROR CONTINUE has been typed).
