in reply to Small Perl quests for a beginner?

Not to sound like a parrot, :), but the exercises in the llama book have helped me tremendously. Also, Every time you learn a new skill, write a small program, to play with and test that specific skill, i.e., when I learned regular expressions, I wrote this little reg ex tester:

#!usr/bin/perl $my_string = ""; $my_regx = ""; # This program tests regular expressions against a match. if ($my_string =~ /$my_regx/x) print qq{Matched: "$&"\n}; # print match print qq~Before match: "$`"\n~; # print data before match print qq|After match: "$'"\n|; # print data after match } else { # do nothing } # end if print "Rockstar Programming Inc. All Rights Reserved\n";

to practice and play around with regular expressions. The same thing for loops, if statements, sub-routines, variables, arrays, hashes, etc. This is a great way to learn, for several reasons,

One, it teaches you the basic skill you're practicing;

Two, you learn basic structure by having to design the little testers;

Three, you learn how to break things into pieces and play with/work with them, which is a skill needed for de-bugging later, more complicated programs;

And four, you can use these little testers you wrote for actually de-bugging your code later. :)

P.S. Umm, the whole "Rockstar Programming" line, should probably be left out, that will only be applicable in the future after I've taken over the world with my software development company, Rockstar Programming ;).

[GotToBTru]: ve been looking at a document we have been sending to a customer for years now
[MidLifeXis]: We don't, at least in this case ;-)
[GotToBTru]: and it includes a reference number that I didnt recognize
[GotToBTru]: I had to dig into the code to find out where it came from .. and it makes no sense
[GotToBTru]: so I emailed my contact asking if we could just stop sending it .. I'm afraid she is going to ask "what is that anyway?"
[MidLifeXis]: heh.
[MidLifeXis]: Most likely it is a code that some undocumented system, hidden behind layers of IT, deep in the bowels of the building under the machine room floor, reads that code to keep a presence switch from going off. :-b
