perl and anonymous hashes
Hey i am coding in perl and i need some help accessing an anonymous hash within an array. When i use Data:umper to print what the array looks like to see what the hash looks like, this is what i get:
Code:
$VAR1 = [
{
'Tree' => 'fir',
'DBH' => '23',
'Height' => '80',
'Growth' => "1.2"
}
{
'Tree' => 'redwood',
'DBH' => '32',
'Height' => '134',
'Growth' => "3.2"
}
];
that isnt completely accurate (i might have missed a space or something) since i couldnt copy it and had to hand type it all out, but you get the point. Anyways i want to access the value in the 'Tree' key but i dont know how to get it. Any help would be much appriciated. Thanks in advance!

alright well i figured out the answer to my own problem because i am special like that
Code:
print "\t\tTree: ",$arrayPlot[0]->[0]->{"Tree"},"\n";
also this is a really stupid quetion i guess, but if i have perl code i wrote a on unix system and i want to turn it into an .exe for a windows system so i can just open up the program and run it, how would i do that?
**EDIT**
so i found a program that does what i want called Perl2Exe. I am wondering how to install this thing on Cygwin. I am a total n00b when it comes to windows and a total n00b when it comes to linux, so help me out please. I also want to update cygwin, but i dont quite get how to do that. Anyways, maybe i should be starting a new thread in the newbie forum, but any help is much appriciated!
