Cbool()
Converst an expression into a boolean. So if the expression is true, i.e. 5 = 5 then it would return True, if it is false, i.e. 5 = 6 then it would return false.
Script:
Sub Main
Dim a, b, c As Integer
Dim check As Boolean
a = 5
b = 5
c = 6
check = CBool(a = b)
MsgBox check 'returns True
check = CBool(a = c)
MsgBox check 'returns False
End Sub
