Currently I've got...

$Count = 192 # some arbitrary constant, or command line argument, or input; > 0

$i = $Count
while (i -= 1) >= 0
# some stuff
end

...In other languages I'd use a counted "for" loop. Is there something more elegant than the above?

Kindly ignore the missing "$" in the conditional expression.

$i.times do |x|
end

$i.downto 0 do |x|
end

Off by one errors included. ;-)

3.downto(0){|i| p i}
