how to use perl

-

sorry total newb questions, gotta start somewhere. got cool book called programming perl , have started weeding through 1,000 pages of it. can write , compile stuff learning? need xcode? also, how can open apps can see code? interested in language , want implement it.
 

perl not compiled language (in traditional sense). save plain text files (you can text edit) , run them in terminal via perl <filename>
