Up to four digits in the source word can be converted. The digits are num-
bered 0 to 3, right to left.
Di: Digit Designator
The digit designator specifies various parameters for the conversion, as
shown in the following diagram.
Digit number:
3 2 1 0
D: First destination word
The converted ASCII data is written to the destination word(s) beginning with
the specified byte in D. Three destination words (D to D+3) will be required if 4
digits are being converted and the leftmost byte is selected as the first byte in
D. The destination words must be in the same data area.
Any bytes in the destination word(s) that are not overwritten with ASCII data
will be left unchanged.
