in reply to Removing elemets from an array

And for completeness, the hash slice approach:

(Nota bene: repeated array elements will be deleted)

DB<109> @arcb = ( 450, 625, 720, 645 ); => (450, 625, 720, 645) DB<110> @arca = ( 625, 645 ); => (625, 645) DB<111> @arcb{@arcb}=(); => (undef, undef, undef, undef) DB<112> @arca{@arca}=(); # EDIT: ehm ... sorry useless line... + => (undef, undef) DB<113> delete @arcb{@arca} => (undef, undef) DB<114> @arcb=keys %arcb => (450, 720)

Cheers Rolf
