Val() function work with some help from the compiler, this way you can pass either an integer or a floating point variable as the second argument. There is nothing in Delphi which is "nothing" for an integer or a floating point value. The closest is using variant instead of simple data types. A variant can be empty. You can also use a pointer. > 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 :-) ) Sorry but I don't clearly understand what you intend to do. Could you explain again, and give a complete example, even if it doesn't compile because of syntax error. -- [EMAIL PROTECTED] The author of the freeware multi-tier middleware MidWare The author of the freeware Internet Component Suite (ICS) http://www.overbyte.be _______________________________________________ Delphi mailing list -> Delphi@elists.org http://lists.elists.org/cgi-bin/mailman/listinfo/delphi
