Pick up a copy of the Perl Cookbook, by Tom Christiansen and Nathan
Torkington (O'Reilly, 1998). It is very good.
It has answers to this and about 300 other common questions. And,
most pleasingly, for most questions the Cookbook includes a discussion
of how the solution is structured, alternative solutions, and relevant
trade-offs.

Is there a good way to take a numeric variable of undetermined length
$var=3423723482309234098;
$var2=3325656;
etc.
and print it out with a comma appropriately placed at every third character
slot from the end, i.e.
3,423,723,482,309,234,098
3,325,656
etc.
