Conversion Instructions Section 5-19
The following is an example of a one-digit encode operation to digit number 1
of R, i.e., here Di would be 0001.
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
beginning 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.
Digit Designator The digits of Di are set as shown below.
Some example Di values and the word-to-digit conversions that they produce
are shown below.
Flags ER: Undefined digit designator, or S plus number of digits exceeds a data
area.
Content of a source word is zero.
Indirectly addressed DM word is non-existent. (Content of *DM word
is not BCD, or the DM area boundary has been exceeded.)
