Jared,
Thanks for the summary. Any comments on where Tcl fits in to the mix?

Let me start off by saying that I like Java. I took a class in it from Sun, and Java is easy. Learning the libs is hard but the language is easy.

I'm going to say something now that may sound counter intuitive:

Learn Perl first. The reason it may seem counter intuitive is that Perl is hard to learn, at least at first. Much easier if you've had exposure to C though.

The reason for learning Perl is that there are many tasks that are easy in Perl that are hard in Java. It's the same old balance: with power comes complexity.

The basics of Perl aren't really *too* hard, just take a little getting used to.

The payoff is big. There is no better language for data munging than Perl. If you need to clean up data for SQL loader files, use Perl. Don't try to do it with PL/SQL or Korn as it is just too much work.

While SQL*Loader allows you to do some very complex things in it, it is *very* difficult at times. Clean your data first.

Need to deal with a lot of text files, search for errors in log files, etc., do it with Perl.

You will also be able to develop Perl code much faster than you can develop Java code. Java is very wordy, Perl can be very terse if you want or require.

Perl makes hard things easy, and impossible things possible. :)

see www.perl.com for articles, downloads and tutorials.

Good first books for the non-programmer are Learning Perl and/or Learning Perl for Win32.
