Functional Description
The Compare Pointer instruction sets the Control Code (
a comparison of two values. The input operands are P-registers.
The compare operations are nondestructive on the input operands and
affect only the
subsequent conditional branching.
The various forms of the Compare Pointer instruction perform 32-bit
signed compare operations on the input operands or an unsigned compare
operation, if the
tions perform a subtraction and discard the result of the subtraction
without affecting user registers. The compare operation that you specify
determines the value of the
