Data Distribution Operation
DISTC(566) copies S to the destination word calculated by adding Of to Bs.
The same DISTC(566) instruction can be used to distribute the source word
to various words in the data area by changing the value of Of.
S
Stack Push Operation
When the leftmost digit (bits 12 to 15) of Of is 9 BCD, DISTC(566) operates a
stack from Bs to Bs+Of-9000. The destination base address (Bs) contains the
stack pointer and the rest of the words in the stack contain the stack data.
DISTC(566) copies S to the destination word calculated by adding the stack
pointer (content of Bs) + 1 to address Bs. The same DISTC(566) instruction
can be used to distribute the source word to various words in the data area by
changing the value of Of.
S is copied to:
Bs + stack pointer + 1.

Bs+ +1
Bs+(m-1)
