Writing on the screen
Well, one more post in the series "Programming perl", which will probably become a weekly, every Wednesday with a brand new post for you. Try to be as regular social gatherings of rio.pm , already a few years occur every second Thursday of the month. But back to the mini-tutorial ... Today we'll talk about how to print things on the screen using perl.
