Use list assignment i.e. for two variables $a, $b: ($a,$b) = ($b,$a)
Type equivalence occurs when two variables are of the same type. For example, if both variables are int (integer variables), they are of equal types. Equivalence can also occur with two different types that are compatible with each other.
First, make sure you have #!/usr/bin/perl at the top. Then, click enter, and type: print "Hello, World!"; After that, save it as name.pl (replace name with whatever you want to name it) and you are all done! Test it out on a web server that supports perl or the perl command line.
Perl is a programming language. Perl is an interpreted programming language. Perl is very useful for shell scripts, application programming, and web applications. Perl is quite easy to learn. Perl can be, but does not have to be, object-oriented. Perl was created by Larry Wall. Perl has probably the best implementation of regular expressions in existence.
There are a number of sites that provide information about how to learn the Perl programming language. They include Learn Perl, Learning Perl and Perl Tutorial Hub. Amazon and other good booksellers have a wide range of Perl books available.

Variables change, constants do not.

Perl was the easiest language to use.The program is a text file, they can easily upload it and pass it around. Perl script is well the same on any platform, so what you wrote locally most likely worked exactly the same on a different machine.
