Used to perform a logical implication on two expressions.
result = expression1 Imp expression2 |
The Imp operator syntax has these parts:
Part | Description |
result | Required; any numeric variable. |
expression1 | Required; any expression. |
expression2 | Required; any expression. |
The following table illustrates how result is determined:
If expression1 is | And expression2 is | The result is |
True | True | True |
True | False | False |
False | True | True |
False | False | True |
The Imp operator performs a bitwise comparison of identically positioned bits in two numeric expressions and sets the corresponding bit in result according to the following table:
If expression1 is | And expression2 is | The result is |
0 | 0 | 1 |
0 | 1 | 1 |
1 | 0 | 0 |
1 | 1 | 1 |
Dim A, B, C, D, MyCheck A = 10: B = 8: C = 6: D = Null ' Initialize variables. MyCheck = A > B Imp B > C ' Returns True. trace MyCheck MyCheck = A > B Imp C > B ' Returns False. trace MyCheck MyCheck = B > A Imp C > B ' Returns True. trace MyCheck MyCheck = B > A Imp C > D ' Returns True. trace MyCheck MyCheck = C > D Imp B > A ' Returns False. trace MyCheck MyCheck = B Imp A ' Returns -1 (bitwise comparison). trace MyCheck |
