Hi Cédric, var S: String; myV : Integer; myCode : Integer;
> Val(S, myV, myCode); works fine until I don't use the 2 var after so it makes a warning Does it? to me you are just passing uninitialized variables....they could be anything! I think you need to re-think why you need to pass nothing or decide what values represent "nothing". also your syntax seems a little odd to me :( Regards, Tim Cédric Joubert wrote: > hi, > > I'm new on the list... happy to see that there is such a list... > > Can you tell me to pass "nothing" to a function/proc that waits for an Var > argument ? > > > Let's take the System > procedure Val(S;var V;var Code:Integer); > > Val(S, 0, 0); OR Val(S, Null, Null); doesnt' work of course > > var > S: String; > myV : Integer; > myCode : Integer; > begin > Val(S, myV, myCode); works fine until I don't use the 2 var after so > it makes a warning (hint) i don't want > > > How may I delete the warning/hint if the myV or myCode argument are never > used after so i don't need a to declare a new var ? > (even i know that the arguments are to be used, of course :-) ) > > Proc "Val" is juste an example... > > Cédric > __________________________________________________ > Delphi-Talk mailing list -> [email protected] > http://lists.elists.org/cgi-bin/mailman/listinfo/delphi-talk > ------------------------------------------------------------------------ > > > No virus found in this incoming message. > Checked by AVG - http://www.avg.com > Version: 8.0.176 / Virus Database: 270.9.11/1820 - Release Date: 11/29/2008 > 6:52 PM > > -- Tim Benham Guildford Computers Tel: 01483 458468 Mobile: 07703 564775 __________________________________________________ Delphi-Talk mailing list -> [email protected] http://lists.elists.org/cgi-bin/mailman/listinfo/delphi-talk
