Passing arrays in and out of procedures

Posted by sonali.birari (sonali.birari), 13 December 2006

Hello

I want to pass either array or list to a procedure.

Requirement:
1) How will one pass array as input to a procedure?
2) How to access the passed array inside the procedure?

It will be of great help if some example is provided for better understanding.

Thanks & Regards,
Sonali

The trick is in the upvar command.

There's a note here on how to do it, and plenty of upvar examples here. There's a complete worked example here too.

Thanks.

It worked for me.

Sonali
