The digits of Di are set as shown below.
Specifies the first digit to receive converted data
16-to-4: 0 to 3
256-to-8: 0 or 1
Number of digits to be converted
16-to-4: 0 to 3 (1 to 4 digits)
256-to-8: 0 or 1 (1 or 2 digits)
Encoding bit (See note.)
0: Leftmost bit
1: Rightmost bit
Process
0: 16-to-4
1: 256-to-8
Digit number: 3210
Note The encoding bit can be specified for version-2 CVM1 CPUs only. For earlier
CPUs, only the leftmost bit can be encoded.

The rightmost two digits of Di must each be between 0 and 3.
All source words must be in the same data area. DMPX(111) requires either 4 or
32 source words, depending on the type of conversion performed.
Note Refer to page 115 for general precautions on operand data areas.
Flags ER (A50003): Content of *DM word is not BCD when set for BCD.
