Data Conversion
Description
Digit Designator

All source words must be in the same data area.
When the execution condition is OFF, DMPX(77) is not executed. When the
execution condition is ON, DMPX(77) determines the position of the highest
ON bit in S, encodes it into single-digit hexadecimal value corresponding to
the bit number of the highest ON bit number, then transfers the hexadecimal
value to the specified digit in R. The digits to receive the results are specified
in Di, which also specifies the number of digits to be encoded.
The following is an example of a one-digit encode operation to digit number 1
of R, i.e., here Di would be 0001.
First source word
0 0 0 1 0 0 0 1
C transferred to indicate bit number 12 as
the highest ON bit.
Result word
C
Up to four digits from four consecutive source words starting with S may be
encoded and the digits written to R in order from the designated first digit. If
more digits are designated than remain in R (counting from the designated
first digit), the remaining digits will be placed at digits starting back at the be-
ginning of R.
The final word to be converted (S plus the number of digits to be converted)
must be in the same data area as SB.
The digits of Di are set as shown below.
Digit numbers: 3 2 1 0
0 0 0 1 0 1 1
Specifies the first digit to receive converted data (0 to 3).
Number of words to be converted (0 to 3)
0: 1 word
1: 2 words
2: 3 words
3: 4 words
Not used.
