                     21: facility.
                     22: iobuf_____ is the address of a 518(10) byte buffer area whose
                     23: contents are maintained by these routines.  Its format is:
                     24: .sp

                     28:        .=.+2           / ptr to next character
                     29:        .=.+512.        / the buffer

                     32: fopen_____ may be called initially to open the file.  On return,
                     33: the error bit (c-bit) is set if the open failed.
                     34: If fopen_____ is never called, get___ will read from the standard
                     35: input file.
                     36: .sp
                     37: getc____ returns the next byte from the file in r0.  The
                     38: error bit is set on end of file or a read error.
                     39: .sp
                     40: getw____ returns the next word in r0.  getc____ and getw____
                     41: may be used alternately; there are no odd/even
                     42: problems.
                     43: .sp
                     44: iobuf_____ must be provided by the user; it must be on a word boundary.
                     45: 
                     46: To reuse the same buffer for another file, it is sufficient
                     47: to close the original file and call fopen_____ again.
