What happens under the hood, must be that the compiled subroutine is loaded into a variable, and that variable is either placed somewhere on the stack or another area, and the way a function works is the same way, just with another syntax.. ?? that would take the exact same amount of clock cycles to reach the subroutine as a call to a function would A function is also 'just' a loaded subroutine, so in effect the runtime does a longjump to the routine.. Am i totally wrong on this ?? best regards from 'melted down' denmark Claus Derlien Frie Funktionfrer - faglig organisation og tvfrfaglig a-kasse - www.f-f.dk *************************************************************************************************************************************** Denne email og alle filer vedlagt som bilag kan indeholde fortroligt materiale, der kun er beregnet for adressaten, og maa ikke udleveres eller kopieres til uvedkommende.
