Hello everybody,

I was wondering about which of these three routines
that are faster:

1)
    ...
    MK=Mouse Key
    MC=Mouse Click
    If MC<>0
      If MC=2
        If MK=3
          ...
        Else
          ...
        End If
      Else
        If MK=3
          ...
        Else
          ...
        End If
    Else
      If MK=1
        ...
      Else
        ...
      End If
    End If
    ...


2)
    ...
    MK=Mouse Key
    MC=Mouse Click
    If MC=2 and MK=3 then ...
    If MC=2 and MK<>3 then ...
    If MC=1 and MK=3 then ...
    If MC=1 and MK<>3 then ...
    ...


3)
    ...
    MICE=Mouse Click
    Rol.b 2,MICE
    Add MICE,Mouse Key
    On MICE Proc ZIP,ZIP,ZIP,ZIP,MICE_5,ZIP,MICE_7,...
    ...

All three has both good and bad sides,but
which one is faster?

I've heard that procedures should be avoided to make
routines faster.Is it true always or is it true only on
events like when a procedure is returning or receiving an
argument?
