A nonnumeric literal is a character-string of 0 to 256 characters.  It
  is delimited on both ends by quotation marks (") or apostrophes (').  A
  nonnumeric literal delimited by apostrophes is treated in the same
  manner as a nonnumeric literal delimited by quotation marks.

  The value of a nonnumeric literal is the value of the characters in the
  character-string.  It does not include the quotation marks (or
  apostrophes) that delimit the character-string.  All other punctuation
  characters in the nonnumeric literal are part of its value.

  The compiler truncates nonnumeric literals to a maximum of 256
  characters.
