For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.
Passing arrays in and out of procedures

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

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

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,

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.
