Thanks for this..

 DN> Not great code, but it should provide a starting point.

It's good, this is the best idea i've had so far :-)
But as i thought there is no way of not supplying a specifier for the 
variables.
I may just have a play with it now :-)
Actually i never did look at pointer's sizes before,and i always thought
that the size of the pointer would be an indicator to the type. 
That theory got killed pretty quick, in a switch(sizeof(ptr)) test.
Oh well, learn s'thing every day...
