In my mail reader, at least, your desired view has the dollar amounts
on a seperate line. that's simple enough:
print "$description\n\$$amount\n";
for maintaining columns, though, see the printf and pack functions.
Both of those can help you print fixed-width fields.
Perl also has built-in forms--see the perlform perldoc.
If none of these quite meets your exact needs, CPAN also has a slew of
templating modules. Text::Template, Text::Templar,
Text::SimpleTemplate, Text::ScriptTemplate, and Text::MicroMason would
all solve your problem in differnt ways depending on how and where you
want to handle the logic and text programatically.
