VB is a Microsoft thing. I don't see why it *couldn't* work
under Linux; it seems like a fairly platform-independent
object model, but then again I have little experience with
it. Microsoft's Visual Basic for Applications (VBA) has
Excel- and Word-specific object models. VBA is actually
pretty awesome: when Excel came out, it pretty well
annihilated the crappy macro language inside of Lotus 1-2-3.
But I digress.

I'd suggest Perl. It gives you shell-programming experience,
and it's also the basis for a large portion of the websites
out there. Plus Perl is very much like PHP, I'm told (I do
all my web stuff in Perl, not PHP), so it probably buys you
PHP without much work.

I've also found that Perl has the smallest gap between "what
comes to the programmer's head" and "what the programmer has
to type". Here's how you'd convert all instances of
<b>[Some text]</b> in a given document into
<strong>[Some text]</b>:

#!/usr/bin/perl
use strict;
use warnings;
my $infile = join '',<>;
$infile =~ s|<b>(.*?)</b>|<strong>$1</strong>|gsmi;
print $infile;

Now if you save that as 'progname.pl', you can run

progname.pl testfile.html

and get the converted file on standard output. Six lines to
do a basic task that *should* take only six lines. Try doing
this in C.

I've heard Python is very good, too, and cleaner that Perl.
It's supposed to be a better language for object-oriented
programming.

One question is: what do you want to do with the languages
you learn? C is best for low-level programming that requires
you to play directly with RAM. C++ is more object-oriented,
but is really a hack -- a good hack, though. (Check out
Stroustrup's "The Design and Evolution of C++" to understand
why it works the way it does. He had no choice.)

The whole world really ought to be OOP, except for a small
number of people who need low-level hardware access. So you
probably ought to learn Python or C++.
