|Do you know where your variables are?|
From your code it looks like you have influence from other structured programming languages. (Are you perhaps thinking that unlink is something like C's free(3) to free allocated memory? You don't need to do that in Perl; it handles garbage collection for you automatically.)
Haha, that's what they said about java... and, well--we all know the truth...
I started with BASIC when I was a wee tot. I only ever learned enough to copy out of the BASIC book. From there I took a VBasic course and learned VB6. From that I was able to apply what I'd learned into automating MANY tasks with VBA. Parallel to that I was trying to learn C++; I've never even gotten a "Hello World" program to work in C++. After that I focused my energy on C# which I grasped rather quickly and banged out several "practice" programs. Also IMPORTANT to note this is when I discovered the "open source" world, and discovered how to shed my Microsucks dependencies...
At this point I've changed schools and majors (I'm a certified EMT... But I needed a way to pay for my paramedic degree...). Enter Computer Science.
Fortunately as a previous Math major I've completed most of the requirements for my CS degree. As a CS Major, our language of study is java... IMHO on of the most klutzyist languages I've studied.
In parallel to starting my CS Major I landed a job. This job promoted me programming where I learned to love Perl.
Anyway... Long Story Short (too late), Out of necessity I've needed to become a Server and Perl Expert over night. Obviously, I still have some learning to do.I'm really not sure how making a hash key = 1 is helpful. I understand making "the whole mess" a key is like making it an array.
I've been studying from "PERL By Examply" By Ellie Quigly. Can you maybe recommend a better book?
