58451          E453           DSKINV
     Takes its information from the bytes in the lower part of page
     three ($300) for operation. The vectors between 58448 and
     58496 ($E450-$E480) are all three-byte vectors; a JMP instruction
     followed by an address in LSB/MSB format.

58454          E456           CIOV
     Page 147: IOCB number times 16 in the X register. The X register
     becomes the CIO channel number. Since the screen is always
     open for channel 0, when using the screen you make the X reg-
     ister 0 as well. Bill Wilkinson says that to output a single charac-
     ter through the CIO instead of an entire buffer (the normal
     occurrence), set the buffer length to 0. This forces the I/O to in-
     put or output a single character only. See COMPUTE!, January
     1985.
