1.1       root        1: APL System commands.
                      2: 
                      3: There are a whole bunch of them.  Most are pretty familiar.
                      4: 
                      5: )DIGITS n
                      6:        sets the number of digits displayed to n, from 1 to 19.
                      7: 
                      8: )FUZZ n
                      9:        sets the fuzz to n.
                     10: 
                     11: )ORIGIN n
                     12:        sets the origin to n, which can be any integer, not just 1 or 0

                     14: )WIDTH n
                     15:        sets APL's idea of your terminal's carriage width.

                     17: )ERASE n
                     18:        gets rid of function or variable named n.
                     19: 
                     20: )SAVE n
                     21:        saves all variables and functions in file named n.
                     22:        The format used is peculiar to APL workspaces and can only
                     23:        be read back in by APL.
                     24:

                     26:        gets the stuff in file n (which must have been saved) back.
                     27:

                     29:        like )LOAD but variables and functions are not erased.  Things
                     30:        in the loaded file take precedence over stuff already in.
                     31:

                     37: 
                     38: )CONTINUE
                     39:        does what you'd expect.
                     40: 
                     41: )OFF
                     42:        exits, as does ctrl/d.

                     45:        reads in a function from file n.  The first line is the header,
                     46:        with no del's.  The full APL\360 header is accepted.  All other
                     47:        lines in the file are lines in the function.  Lines are impli-
                     48:        citly numbered, and transfers are as usual.There are no labels.

                     64:        toggles a debugging switch, which can produce vast amounts
                     65:        of hopelessly cryptic output.
