PERL is a programming language (♦ see DEF) multiplatform, created in 1987.

PERL essentially allows you to conceive processing programs.

→ Let's start with very simple codes. The more you progress, page after page, the more sophisticated the scripts will be. However, you must go over 30 to 40 pages per level, before moving on to the next step...

→ In order to evaluate your codes, click on the icon on the left at the bottom of the page (gears), then choose a compiler from the list that will be open in another tab. Finally, test your work.

NOW REPRODUCE AND IMMERSE YOURSELF!
