VBScript AND operator

Dear Members,

This is known issue and just wanted to check an alternate solution for AND operator.

In If Condition i am using AND and i wanted to exit condition if first condition is false.

If(a() AND b())

End If

This way it executes both functions and verify later. But if a() returns false i need to exit from If. I know in VB AND executes both and later validates. Any alternate solution please for such validation?

Thanks in advance.
