$var_total = eval($var_tmp);
will do what you want.

Also, alt.comp.lang.perl & comp.lang.perl are very rare if not virtually
extinct news groups. I don't think too many people get them. Though there
seems to be SOME activity in those two said groups...

Or is alt.comp.lang.perl just a lesser known group?

alt.comp.lang.perl is a legit alternative to the mainstream Perl groups.
comp.lang.perl has been decommissioned many years ago -- it *shouldn't*
exist anywhere, but a sizeable minority of news server still carry it.

and what would be the mainstream perl newsgroups?

Please see "perldoc -q usenet".
And don't top-post-full-quote!

Unfortunately, my server carries both :(
Thank you for the info though.

wtf is "perldoc -q usenet"?
Just tell me the newsgroup please.
I'm in windows right now, though I do have several Linux boxes and I work
solely in SunOS5 at work.

Yes, I have the windows perl port and use it regularly.
Works great. Also have the xemacs port for windows :)
I know, I am hearing your scream now :)

A reference to the FAQ that comes with perl.

The FAQ you are supposed to check *before* posting.

The FAQ that specifically answers your question.

Run the command:

perldoc -q usenet

on one of the machines with perl on it (and set up to include the perl bin
directory in your path) for the answer to your original question.

I see you ignored the second statement. Hope you don't have any
perl quesions later, since I suspect a whole bunch of very knowledgable
and helpful folk won't be reading your posts...
