The range() function has the ability to generate a range from one number (or character) to another.  It states in the documentation that if the first number (character) is greater than the second, it creates a decreasing range.  However, the problem is, sometimes you don't want it to switch range order, so it would be nice to have a third parameter which states the direction or states whether you want it to auto flip.  Hence, if I did

range(9, 0, ASC)

it would generate an empty array...

or prehaps I could do

range(9, 0, false)

for not autoflipping.
