You're right when you say I should have used freshly reinitialised input. But where does map destroy the input array?

EDIT: Okay, I've got it now. Thanks for your help.

    The array is not exactly deleted, but the elements are reduced to empty strings:

    DB<139> sub my_uc { my $c = shift; return uc($c); } DB<140> my_uc() DB<141> @a = map my_uc, a..c => ("", "", "")

    keep in mind no argument means $c is undef!

    Cheers Rolf
