You cannot call a near function via a far pointer. If you find way to cast the 
pointer, the called functions parameters will be addressed wrong and 
a return from the called funtion crashes you program. Near functions in a large 
model should never be used with function pointers. If you need the pointer, you 
should strip off the "near" attribute.
