Forum OpenACS Q&A: Re: How to upvar an array in a recursive procedure

Posted by Simon Carstensen on
Dave Bauer's code looks like something I'll want to go with, but for the sake of learning, let's figure out what's wrong with my code.
get_tree $children [lindex $elements $i] $parent $level
gives me this error:
can't read "parent": variable is array
Your suggestion makes sense to me and I've tried it before. Right now I'm passing one element and I guess the question comes down to how I pass the whole array (of course likewise with the recursive call to get_tree).
