| A routine or subroutine also referred to as a function, procedure, and subprogram is a portion of code that may be called and executed anywhere in a program. For example, a routine may be used to save a file or display the time. Instead of writing the code for these commonly performed tasks, routines are made and called when these tasks need to be performed. Below is a basic example of a Perl subroutine. &hello;
sub hello {
print "Hello World!\n";
} In the above example, a user could call the hello subroutine (in this example, by typing &hello;) anywhere within the program and have the program print Hello World!. Also see: Call, DLL, Function, Programming definitions,
