No joking, unless you started it somewhere earlier. The OP didn't want 
to compare to a string, yet your "example" forces him to exactly do 
that. If not, would you care to show us the fulfillment of "the 
parameter IS REALLY NOT A STRING, but a direction" in your example? Thanks.

You see, it seems that you agreeing to be wrong is something your are so 
adamantly refusing to acknowledge that I'm inclined to believe that in 
the event of this really happen one day, a great rift in the very fabric 
of space and time would appear, and the world would end. If this 
conversation was in my native language and not in yours, I'd might give 
it a shot, just to see what really happens. But as it isn't, and I guess 
everybody else except you knows that your wrong - I wont.

HTH,

Diez
