6.3.3 Double-Word (32 bits) Data

Double word data is 32-bit numerical data used by basic instructions and application instructions.
Word devices and bit devices designated by digit designation can be used as double word data.
 When using bit devices
Digit designation can be used to enable a bit device to deal with double word data.
Digit designation of bit devices is done by designating "Number of digits" and "Initial number of bit device".
Digit designation of bit devices can be done in 4-point (4-bit) units, and designation can be made for K1 to K8.
For example, if X0 is designated for digit designation, the following points would be designated:
 K1X0: The 4 points X0 through X3 are designated
 K5X0: The 20 points X0 through X13 are designated
 K2X0: The 8 points X0 through X7 are designated
 K6X0: The 24 points X0 through X17 are designated
 K3X0: The 12 points X0 through XB are designated
 K7X0: The 28 points X0 through X1B are designated
 K4X0: The 16 points X0 through XF are designated
 K8X0: The 32 points X0 through X1F are designated
