As soon as `undef` is used as value, your code will break. Better be safe than sorry. Debugger demo: `DB<2> $h{a}=1 DB<3> $h{b}=undef DB<4> x grep {defined $h{$_}} "a".."d" 0 'a' DB<5> x grep {exists $h{$_}} "a".."d" 0 'a' 1 'b' DB<6>` [download] Cheers Rolf _{(addicted to the Perl Programming Language :) see Wikisyntax for the Monastery}	[reply] [d/l] [select]
