Module 9054 Conversion from ASCII/hexadecimal → binary
Module 9054 converts strings of ASCII-coded hexadecimal values into a block
of binary values in the word-marker range. The string in the specified string
memory is interpreted as a sequence of ASCII-coded hexadecimal numbers
and converted into a block of corresponding binary bytes. Two ASCII
characters produce one binary byte. The control saves the binary block
beginning at the specified address in the word-marker range.
Call:
PS B/W/D/K <String address in which the hexadecimal value is saved>
PS B/W/D/K <Word address from which the control saves the binary
values>
