Static variable inside procedure
how to write a static variable inside the procedure? consider the following code, every time i call this procedure it will redeclare the variable x that's what i dont want to. i want the variable to be declare at the first call and keeping value after the rest of the calls.
procedure Test;
var
x : integer;
Begin
inc(x) //x will be the same value every time get call. i want x to be increase every call.
End;
procedure Test;
var
x : integer;
Begin
inc(x) //x will be the same value every time get call. i want x to be increase every call.
End;
Well, I answered this question and it is still in the Unlocked section?!?!?! What's wrong??
use global variable or define new class (Trigger for example)
and get your counter every time!
and get your counter every time!
Sorry Viktor - you are wrong. (Although if it was for a static member in a CLASS or METHOD,. you would be right).
Do it like this:
procedure Test;
const
x : integer = 0;
Begin
inc(x) //x will be increased every call.
End;
Cheers,
Raymond.

Yes, Raymond seems to be right.
I always wondered why Delphi likes something like this:
procedure blaBla;
const x : integer = 0;
...
and refuses to accept something like this:
procedure blaBla;
var x : integer = 0;
...
Now I know (thanx, Raymond) that the "const" declaration has a special meaning if used locally.

Yes, Viktor, that's really strange! Why is this question still in the unlocked area???
Perhaps the XX system is getting more and more intelligent so that it now is able to detect that your answer is wrong... :-)))

ASKER
thank Raymond......now post it as answer...i will Accept it...
I forgot about the fucken typed constants in Delphi.... I really hate the way that they made it 'cuz you can never be sure it's a constant... I just hate that future of Delphi...
