Hi guys,

Does passing a pointer to a function effect performance, as opposed to
having the contents of said pointer global or local ? 
Also, does re-entrancy mean, that one can have multiple instances of a 
function/program ?  Yep, still trying to learn the right terminology.
 
                                  
thanks,
