Sample program
When CIO 0.00 is ON in the following example, ASC(086) converts three hexadecimal digits in D100
(beginning with digit 1) into their ASCII equivalents and writes this data to D200 and D201 beginning
with the leftmost byte in D200. In this case, a digit designator of #0121 specifies no parity, the starting
byte (when writing) = leftmost byte, the number of digits to read = 3, and the starting digit (when
reading) = digit 1.
