You don't have to use upvar

Code:

proc bla {bla bla bla} {  #call proc 2 and catch the result   set result [bla2 bla]}proc bla2 {bla} {  #do the sql querie and return the result  return $result}

... easy way to do it

Well thanks it's nice to know some-one is trying to be helpfull. But it still doesn't give me any idea on how uplevel works. As I little by little understand more of TCL i still have a hard time figuring things out by meself.

It's just like the mann pages, if you are not native english or have studied it it's very hard to read. And i'm not natvie english or have studied it
From the man pages (www.hume.com/html84/mann/upvar.htm) i can understand you can only use uplevel is the first letter of your variable is a # or a digit.

But after that it's all some nice english [censored] for me. Are these mann pages also avalible in Dutch or could some-one explain it to me in more simple words. Because i would like to know what i'm doing. With two hours of coding i might get it to work but then i still don't know what i'm doing.

Because i can't get it to work (i think it's me )

Yes, upvar i think is what you are looking for.

upvar - Create link to variable in a different stack frame

or hmm.. uplevel - Execute a script in a different stack frame?

This will change it into a global variable.
In that case it tought the value of the variable will not be emptyd as the proc ends.

But then again as i'm thinking i can drop it myself ofcource.

But can't this be done during the running of the procs only.
Like using the Return function or the upvar and getvar ?

From 1 proc i call another proc that makes a sql querie.
I want to give the value of this querie back to the first prog. So the first proc can uses this value.

Can anyone tell me how to do this.
