Here's one for fun...

SEPARATION, s = 32, 'helloha'
(my_letters = [0, 3]).each {|b| s[b] -= SEPARATION}
puts s

...it's goofy, because I'm golfing and also trying to be descriptive
at the same time :-)

Of course, I'm making a large assumption that the letters to be
capitalized are based on position.

Here's a contrived one...

include 'matrix'
(Vector[*'helloha'.unpack('C*')] - Vector[1,0,0,1,0,0,0] * 32).to_a.pack('C*')

...umm, ugly.
