in reply to How to I retrieve a specific key/value from a hash?

Basically what you're trying to do is create similarly named variables, right? It looks like you're trying to concatenate the base for the variable name with the number, and that's not going to work. You could use an associative array...especially since you seem to be using numbers as the differentiating factor in your naming scheme.

Thus, you can go about it like this:

my (%graphic, %url); for ($i=0; $i<2; $i++) { $graphic{$i} = $foo; $url{$i} = $bar; }

Then when you wish to print, say, the second graphic, you would use:

print $graphic{2};

Hope this was of some help to you.
