sub

See the current Perl documentation for sub.

Here is our local, out-dated (pre-5.6) version:


sub - declare a subroutine, possibly anonymously



sub BLOCK

sub NAME

sub NAME BLOCK



This is subroutine definition, not a real function per se. With just a NAME (and possibly prototypes), it's just a forward declaration. Without a NAME, it's an anonymous function declaration, and does actually return a value: the CODE ref of the closure you just created. See the perlsub manpage and the perlref manpage for details.
