perl subroutine call

Hi, I'm just learning perl and I was wondering if anyone could help clear this up for me. Say we had something like this

Code:

sub something {
    ....
}
something;
&something;

Is there a difference between the last two statements?

If you use the '&', the call is restricted to subroutines defined in the script you're running and cannot run built-in commands.

So:

Code:

#!/usr/bin/perl

sub print {
  printf("This is a local function\n");
}

print ("This is a built-in function\n");
&print ();

Ah, gotcha. Thanks
