What's the opposite of chr() in Ruby?

In many languages there's a pair of functions, chr() and ord(), which convert between numbers and character values. In some languages, ord() is called asc().

Ruby has Integer#chr, which works great:

>> 65.chr

Fair enough. But how do you go the other way?

"A".each_byte do |byte|
   puts byte



and that's pretty close to what I want. But I'd really rather avoid a loop -- I'm looking for something short enough to be readable when declaring a const.


If String#ord didn't exist in 1.9, it does in 2.0:

"A".ord #=> 65

Am I missing something about LINQ?

c# sql linq

I seem to be missing something about LINQ. To me, it looks like it's taking some of the elements of SQL that I like the least and moving them into the C# language and using them for other things.
