Portability Function: Performs an effective BIT-WISE store under mask.
USE IFPORT
result = CSMG (x,y,z)
x, y, z |
(Input) INTEGER(4). |
The result type is INTEGER(4). The result is equal to the following expression:
(x & z) | (y & ~z )
where "&" is a bitwise AND operation, | - bitwise OR, ~ - bitwise NOT.
The function returns the value based on the following rule: when a bit in z is 1, the output bit is taken from x. When a bit in z is zero, the corresponding output bit is taken from y.
