This function is for BASIC compatibility. It is not available in pure JavaScript projects.

Result = x Imp y

Description

Imp returns the logical implication of two expressions. Logical implication returns TRUE if x implies y. Imp also does a bitwise comparison of two numeric expressions.

Table 13: Logical Implication

x y Implication
True/1 True/1 True/1
True/1 False/0 False/0
False/0 True/1 True/1
False/0 False/0 True/1

Example (Basic)

Rem Imp Example
'Imp preforms logical and bitwise implication
Dim Test1, Test2, Test3, x, y
x = 3
y = 5
Test1 = x < 0 Imp y < 10
Test2 = x > 0 Imp y > 10
Test3 = x < 0 Imp y > 10
Print "Logical:"
Print "  x < 0 Imp y < 10 = " & Test1
Print "  x > 0 Imp y > 10 = " & Test2
Print "  x < 0 Imp y > 10 = " & Test3

Output

Logical:
  x < 0 IMP y < 10 = True
  x > 0 IMP y > 10 = False
  x < 0 IMP y > 10 = True
