I would think for such a simple program no need to loop, but just simple if control statements would suffice. s;;5776?12321=10609$d=9409:12100$xx;;s;(\d*);push @_,$1;eg;map{print chr(sqrt($_))."\n"} @_;	[reply]

Sorry, I meant to say "That's why the looping is needed if you use a hash." Of course, you could just do `sub get_score { my ($score) = @_; return 'A' if $score >= 90; return 'B' if $score >= 80; return 'C' if $score >= 70; return 'D' if $score >= 60; return 'F'; }` [download]	[reply] [d/l]

How do I represent the values and keys in a loop or conditional statement?	[reply]

How do I represent the values and keys in a loop or conditional statement? You gets the keys and values of a hash using `keys` and `values`. There is various documentation throughout the internet: keys and values. I'm not sure if `map` counts as a loop, but if it does, then this has hash values in a loop and a conditional (or two): `sub get_grade { my $score = shift; my $grade = 'Ungraded'; $score = 0 unless $score =~ /^\d+$/; map { $grade = $grade_scores{$_} if $score > $_ } sort keys %grade_s +cores; $grade; }` [download] -=( Graq )=-	[reply] [d/l] [select]
