Hi Ian,

I understand your point but I meant that 
 3
1 2
was the way you count the pins and it also showed the
direction.
I thought we were talking in general becasue 1 2 3 can
be also
 2
1 3

What function will be attached to these pins depends
on the component and it can be a letter or a number as
you wish.
