The [IMP](IMP) logical operator converts the result of two comparative values and returns a bit result.
|
||
|
||
## Syntax
|
||
|
||
> result = firstValue [IMP](IMP) secondValue
|
||
|
||
## Description
|
||
|
||
* Returns a different result from [AND](AND), [OR](OR) or [XOR](XOR) - see truth table below.
|
||
* Evaluates if firstValue ***imp**lies* secondValue.
|
||
**If firstValue is true then secondValue must also be true.
|
||
**So if firstValue is true, and secondValue false, then the condition is false, otherwise it is true (see table below).
|
||
|
||
The results of the bitwise logical operations, where *A* and *B* are operands, and *T* and *F* indicate that a bit is set or not set:
|
||
|
||
| A | B | | [NOT](NOT) B | A [AND](AND) B | A [OR](OR) B | A [XOR](XOR) B | A [EQV](EQV) B | A [IMP](IMP) B |

| T | F | | T | F | T | T | F | F |
|
||
| F | T | | F | F | T | T | F | T |
|
||
| F | F | | T | F | F | F | T | T |
|
||
|
||
**[Relational Operations](Relational-Operations) return negative one (-1, all bits set) and zero (0, no bits set) for *true* and *false*, respectively.**
|
||
This allows relational tests to be inverted and combined using the bitwise logical operations.
