                 'Tip'  checks to see if there is any terminal input pending.
                 If terminal input is waiting to be  read,  'tip'  outputs  a
                 "1".  If no terminal input is waiting to be read, 'tip' out-
                 puts a "0".

                 'Tip' is most commonly used with the 'if' command.

                 Should  probably  be able to check an assigned terminal line
                 for pending input.
