Portability Function: Performs a bit-level test for integers.
USE IFPORT
result = BIT (bitnum, source)
bitnum |
(Input) INTEGER(4). Bit number to test. Must be in the range 0 (least significant bit) to 31 (most significant bit). |
source |
(Input) INTEGER(4) or INTEGER(8). Variable being tested. |
The result type is logical. It is .TRUE. if bit bitnum of source is 1; otherwise, .FALSE..
