Basic perl syntax script, can be run from shell via “#!” header: #! usr bin perl print “hello, world\n”; simplest program consists of sequence of statements (like most imperative pls), separated by semicolons ‘;’ (note: last semicolon is optional) there are built in functions subroutines commands, like “print”.

Each lab contains exercises to practice specific perl scripting concepts. the labs progress from simple scripts that print text to scripts that perform calculations, accept user input, define subroutines, and more. the document explains how to set up a perl script and run it on a linux system. We believe perl 6 is a leading modern programming language and are advocating perl 6 to be the new language for teaching introductory programming (and to replace python).
