Nullifying the declared variables automatically?

Marc'Antonio Alessi, CAB2k, zeha, Doug Broad, hendle, Jeff Misher: Thank you all for replying.

Since I was unable to get connected for these days, I could not respond.

Of the responses from Michael Puckett, BillZ and Marc'Antonio Alessi, I personally felt that BillZ's method would be a better choice. I would welcome anybody who would convince me for other suggestions too. Yet, I have to work for some more time with these responses.

This is a subject that effects every one.
When certain codes run into 1000's of lines, searching for variables becomes a hectic task.
My feeling is, through automation of this activity (though this can induct some lazyness factor into us), we can ensure that we do not miss any variable.

I would like to see more suggestions / discussions on this issue to better the current status of this issue.

Thanks,

It is not ever an issue unless the code is written poorly. I agree with
Doug: the variables should be declared local at the time the program is
written. It's inexcusable, IMHO, to allow "1000's of lines" of code to
develop without managing the variables properly.

 

I agree with Tom,
I use this method to "double check" my programs after completion to see if I missed localizing any variables.
I usually list my vars as I go and rem them out if I need to see the values at runtime.

I agree with Doug.

Doug, Marc, BillZ,
In principle and as an ideal programming scenario, I agree with all of you.
Certain times, when we observe that the localisation has not been performed on our old programs when we were unmatured as today, and programs made by some one else unprofessionaly, we tend to become lazy to modify such programs!!!
