Data Movement Instructions Section 3-7
Description DIST(080) copies S to the destination word calculated by adding Of to Bs.
The same DIST(080) instruction can be used to distribute the source word to
various words in the data area by changing the value of Of.
Flags
Precautions Be sure that the offset does not exceed the end of the data area, i.e., Bs and
Bs+Of are in the same data area.
Example When CIO 0.00 is ON in the following example, the contents of D100 will be
copied to D210 (D200 + 10) if the contents of D300 is 10 (0A hexadecimal).
The contents of D100 can be copied to other words by changing the offset in
D300.
