                      5: ``system commands'' in \*a.

                     23: All system commands are preceeded
                     24: by a right parenthesis.
                     25: As an example,
                     26: the following is a typical
                     27: entry into \*a:
                     28: .sp
                     29: $ apl

                     39: (the underline character ``\_''
                     40: represents the ``cursor''
                     41: on the terminal).
                     42: The ``)lib'' command could then
                     43: be typed:

                     48: Commands which specify action
                     49: are composed of the command
                     50: name
                     51: and some other value.
                     52: For instance,
                     53: to set the output width
                     54: (number of characters per line

                     56: to 64,
