《Word shift right》
Function & Action
z The instruction copies n2 source devices to a word stack of length n1. For each addition
of n2 words, the existing data within the word stack is shifted n2 words to the left/right.
Any word data moving to a position exceeding the n1 limit is diverted to an overflow
area. The word shifting operation will occur every time the instruction is processed unless
it is modified with either the pulse suffix or a controller interlock.
