User’s Manual
Eleven bytes are required for this operation.
Figure 22. Shifting of BCD Digits/Bytes
Example Four:
One number is to be subtracted from another number, both of which are in
packed BCD format and are of equal but varying length. The result is stored
in the location of the minuend. The operation is programmed as follows:
SUBDEC:LD
