Imp Operator Example

This example uses the Imp operator to perform logical implication on two expressions.

  Dim A, B, C, D, MyCheck
A = 10: B = 8: C = 6: D = Null   ' Initialize variables.
MyCheck = A > B Imp B > C   ' Returns True.
MyCheck = A > B Imp C > B   ' Returns False.
MyCheck = B > A Imp C > B   ' Returns True.
MyCheck = B > A Imp C > D   ' Returns True.
MyCheck = C > D Imp B > A   ' Returns Null.
MyCheck = B Imp A   ' Returns -1 (bitwise comparison).
