IMP
From QB64 Wiki
The IMP logical operator converts the result of two comparative values and returns a bit result.

Syntax
 result = firstValue IMP secondValue
Description
 Returns a different result from AND, OR or XOR.
 Evaluates if firstValue implies 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).
