Subroutines
Defining Subroutines

  • You can reuse a segment of Perl code by placing it within a subroutine

  • The subroutine is defined using the sub keyword and a name

  • The subroutine body is defined by placing code statements within the { } code block symbols
      sub MySubroutine
      {
      	# Your Perl code goes here.
      }
      

  • Subroutines may be recursive (call themselves)
