Re: Pointer puzzle

[Jon Paris <jon.paris@xxxxxxxxxxxxxx>]

Isn't this an impossible cyclic reference?

wInfAdh is based on the address contained in wPtr_In

But wPtr_In = %ADDR ( wInfAdh );

Catch 22 - it can never get an address (unless assigned elsewhere) and  
the eval is a no-op which will never change the value.

Either that or it is too early in the morning.
