in thread sub argument passing? (TIMTOWTDI)

#prototyped to explicitly state acceptable arguments sub addstuff($$$); ... #gives error if too few or too many arguments #(or arguements of wrong type)


>perl -wMstrict -le "my @ra = (99 .. 199); ;; sub S ($$$) { my $A = shift; my $B = shift; my $C = shift; ;; return $A + $B + $C; } ;; print S 1, 2, @ra; " 104

Maybe better read Far More than Everything You've Ever Wanted to Know about Prototypes in Perl -- by Tom Christiansen first, then generally avoid prototypes.

    Thanks AnomalousMonk, I am following your advice and already seeing some issues that I'll run into with using Perl's prototyping such as it is.

    'Enjoyable light reading' indeed, protist! Maybe just enjoyable ;)

    Strange things are afoot at the Circle-K.
