I agree with your point, as I am a newbie so not that much confident on 
the methods how are they defined in the docs.I tried to understand a bit 
by test code,nothing in my HEAD! :( here is a small code for Pack() 
method of Array class instance.

irb(main):001:0> n = [ 65, 66, 67 ]
=> [65, 66, 67]
irb(main):002:0> n.pack("CCC")
=> "ABC"
irb(main):003:0> n.pack("ccc")
=> "ABC"
irb(main):004:0> n.pack("sss")
=> "A\x00B\x00C\x00"
irb(main):005:0> n.pack("SSS")
=> "A\x00B\x00C\x00"
irb(main):006:0> n.pack("qqq")
=> 
"A\x00\x00\x00\x00\x00\x00\x00B\x00\x00\x00\x00\x00\x00\x00C\x00\x00\x00\x00\
x00\x00\x00"
irb(main):007:0> n.pack("QQQ")
=> 
"A\x00\x00\x00\x00\x00\x00\x00B\x00\x00\x00\x00\x00\x00\x00C\x00\x00\x00\x00\
x00\x00\x00"
irb(main):008:0>

Now here you can see that I used directives as `c` and `C`;`q` and `Q` . 
But looking at the console output i didn't get any differences. But I 
know there should be,so need your help to pin point me,as you are 
experienced! I always obey your guide,directions n all.
