I doin't know about variable names, but you can have these chars in
*handler* names:

  ? (question mark)
  ` (backquote)
  _ (underscore)
  @ (at-sign)
  # (pound sign)
  $ (dollar sign)
  '  (single quote)

So you can do this:

 on DoIt?
  answer "Hello"
 end DoIt?

or

 on Cash$Check
  -- cash check
 end Cash$Check

However as many have said, RunRev may use these special chars in the future
so I generally avoid everything but the underscore.
