Limitations Di must be within the values given below
All destination words must be in the same data area.
Description When the execution condition is OFF, ASC(86) is not executed. When the
execution condition is ON, ASC(86) converts the designated digit(s) of S into the
equivalent 8-bit ASCII code and places it into the destination word(s) beginning
with D.
Any or all of the digits in S may be converted in order from the designated first
digit. The first digit, the number of digits to be converted, and the half of D to re-
ceive the first ASCII code (rightmost or leftmost 8 bits) are designated in Di. If
multiple digits are designated, they will be placed in order starting from the des-
ignated half of D, each requiring two digits. If more digits are designated than
remain in S (counting from the designated first digit), further digits will be used
starting back at the beginning of S.
Refer to Appendix I for a table of extended ASCII characters.
Digit Designator The digits of Di are set as shown below.
Specifies the first digit to be converted (0 to 3).

0: 1 digit
1: 2 digits
2: 3 digits
3: 4 digits
First half of D to be used.
0: Rightmost 8 bits (1st half)
1: Leftmost 8 bits (2nd half)
Parity 0: none,
1: even,
2: odd
