From Webster's Revised Unabridged Dictionary (1913) [web1913]:
   J \J\ (j[amac]).
      J is the tenth letter of the English alphabet. It is a later
      variant form of the Roman letter I, used to express a
      consonantal sound, that is, originally, the sound of English
      y in yet. The forms J and I have, until a recent time, been
      classed together, and they have been used interchangeably.
  
      Note: In medical prescriptions j is still used in place of i
               at the end of a number, as a Roman numeral; as, vj,
               xij. J is etymologically most closely related to i, y,
               g; as in jot, iota; jest, gesture; join, jugular, yoke.
               See {I}. J is a compound vocal consonant, nearly
               equivalent in sound to dzh. It is exactly the same as g
               in gem. See Guide to Pronunciation, [sect][sect] 179,
               211, 239.

From The Free On-line Dictionary of Computing (15Feb98) [foldoc]:
   J
  
      A derivative and redesign of {APL} with added features and
      control structures.   J is {purely functional} with {lexical
      scope} and more conventional control structures, plus several
      new concepts such as {function rank} and {function array}s.   J
      was designed and developed by Kennneth E. Iverson and Roger
      Hui .   J uses only the {ASCII}
      character set but has a spelling scheme that retains the
      advantages of {APL}'s special alphabet.   J is a conventional
      procedural programming language but can be used as a {purely
      functional} language.
