Di must be within the values given below.
All destination words must be in the same data area.
DM 6144 to DM 6655 cannot be used for D.
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.
