1.1     ! root        1: .th APL VI 5/19/76
        !             2: .sh NAME
        !             3: apl \*- apl interpreter
        !             4: .sh SYNPOSIS
        !             5: .bd apl
        !             6: .sh DESCRIPTION
        !             7: This is the really improved APL interpreter.  It puts the
        !             8: terminal into a funny mode, so watch out.  If it blows up, push
        !             9: the single/multi page button to switch back.
        !            10: .s3
        !            11: All of the operators are exactly as in apl\\360.  Overstrikes are often
        !            12: required, and they work (use space, not cursor right).  The keyboard is
        !            13: just the same as a 2741 apl keyboard.
        !            14: .s3
        !            15: Function definition is not what you would expect.  Functions are loaded
        !            16: from files.  The first line of the file is the function header, as you
        !            17: would expect it but with no del.  The rest of the file is the lines
        !            18: of the function.  Lines are numbered, but there's none of the
        !            19: square bracket jazz.  If you say )READ FILE it will load the function
        !            20: in that file.  If you say )EDIT FILE it will put you in the
        !            21: unix editor to change that file. Upon exit, it will read the file in
        !            22: as though by )READ.
        !            23: .s3
        !            24: All of the usual operators are available, including domino.
        !            25: Also available are monadic encode and epsilon.
        !            26: .sh FILES
        !            27: apl_ws \*- temporary workspace file.
        !            28: .s3
        !            29: continue - continue workspace
        !            30: .sh "SEE ALSO"
        !            31: apl.2 \*- synposis of system commands
        !            32: .sh BUGS
        !            33: I don't know of too many, but mail any trouble reports to jrl.
        !            34: .s3
        !            35: Interpreter occasionally blows up, giving core images.
        !            36: .s3
        !            37: Character comparisons don't work (but try concatenating
        !            38: a character vector to a numeric vector and vice versa.)
        !            39: .s3
        !            40: Many mixed functions take less general arguments than
        !            41: you might expect.  Then again any integer origin is allowed.
