Conversion Instructions Section 3-11
Di: Digit Designator
The digit designator specifies various parameters for the conversion, as
shown in the following diagram.
D: Destination word
The converted hexadecimal digits are written into D from right to left, begin-
ning with the specified first digit. Any digits in the destination word that are not
overwritten with the converted data will be left unchanged.
Operand Specifications
Description HEX(162) treats the contents of the source word(s) as ASCII data represent-
ing hexadecimal digits (0 to 9 and A to F), converts the specified number of
bytes to hexadecimal, and writes the hexadecimal data to the destination
word beginning at the specified digit.
An error will occur if the source words contain data which is not an ASCII
equivalent of hexadecimal digits. The following table shows hexadecimal dig-
its and their ASCII equivalents (excluding parity bits).
3 2 1 0Digit number:
Specifies the first digit in D to receive converted data (0 to 3).
Number of bytes to be converted (0 to 3)
0: 1 digit
1: 2 digits
2: 3 digits
3: 4 digits
0: Rightmost byte
1: Leftmost byte
Parity 0: None
1: Even
2: Odd
First byte of S to be converted.
