When CIO 000000 is ON in the following example, the 6 words of ASCII data
starting at D00010 are converted, two words at a time, to numerical data. The
converted numerical data is stored in the DM Area starting at D00100.
■ Example 2: Converting ASCII Data in BCD Format to Hexadecimal Data
When CIO 000001 is ON in the following example, the ASCII characters in
