      Suggestion for lines on investigation welcomed

OH Chilly Monk,
If I want to know the number of elements in an array I'd try one of two things:

# assume two arrays with a number of elements # @rray1 & @rray2 my $elements_1 = scalar @rray1; # or my $elements_2 = $#rray2 + 1;
Either of the two will work.

Eily used google. The lazy internet equivalent of grep
[karlgoethebier]: He!
[Eily]: Discipulus pretty much all oneliners are killing. Do you imagine how many people could be working if you asked them to do the same thing in C each time ? :P
