looking at your list a hash seems like a better option, the hash will be like
%hashlist = (
a => 3,
b => 5,
c => 8,
d => 9,
e => 2,
f => 0);
the reason being, you are associating the numeric values (3, 5, 8 etc.) to the
characters (a, b, c etc.)
a hash (associative array) would be more useful here. Is my assumption correct?
To access the element 'd' you will say $hashlist{d}
You can get more information on hashes from perldoc perldata
