Practical Perl Programming PDF VERSION of PERL NOTES AVAILABLE FOR DOWNLOAD ( Local Students ONLY ). HTML PERL NOTES. A. D. Marshall 1999-2005. Perl is a programming language which can be used for a large variety of tasks. A typical simple use of Perl would be for extracting information from a text file and printing out a report or for converting a text file into another form. But Perl provides a large number of tools for quite complicated problems, including systems programming. Perl is implemented as an interpreted ( not compiled ) language. Thus, the execution of a Perl script tends to use more CPU time than a corresponding C program, for instance. On the other hand, computers tend to get faster and faster, and writing something in Perl instead of C tends to save your time. One of the oddities of the language is that its name has been given quite a few definitions. Originally, Perl meant the Practical Extraction Report Language. However, programmers also refer to is as the Pathologically Eclectic Rubbish Lister. Or even, Practically Everything Really Likable. Perl is free. The full source code and documentation are free to copy, compile, print, and give away. Any programs you write in Perl are yours to do with as you please; there are no royalties to pay and no restrictions on distributing them as far as Perl is concerned.
