Isn't this an impossible cyclic reference?

wInfAdh is based on the address contained in wPtr_In

But wPtr_In = %ADDR ( wInfAdh );

I admit it didn't seem logical. The pointer has the value *NULL which I think is what I should pass to the program that changes it.
Could I just pass the pointer without initialising it?

Either that or it is too early in the morning.

Too late in the afternoon!
