in reply to I use return on a subroutine

Since perl allways returns the value of the last expression, I usually just states $something if the sub's supposed to return some object.

For subs that prints stuff, I leave it to print() to decide.

If an error occurs, I use return 0 after setting an error value if possible.

    Interesting... I do it the other way around!
    my $txt2print = MySub('This text') or warn('MySub said 0'); print $txt2print; sub MySub { my $txt = shift; $txt = { do something here } or return(0); return($txt); }
    or is that what you where saying all along?
      Sometimes I do this too. I guess it's just a matter of preference. Does anyone have a reason to use one or the other?
