        !            10: .SH DESCRIPTION
        !            11: .I aplcvt
        !            12: performs the necessary transformations
        !            13: to produce a VAX format workspace from
        !            14: a PDP-11 format workspace,
        !            15: and
        !            16: .I "vice versa."
        !            17: The workspace formats differ because
        !            18: the word sizes of the two machines
        !            19: are different;
        !            20: hence,
        !            21: pointers have different lengths.
        !            22: In general,
        !            23: any PDP-11 workspace can be converted
        !            24: to VAX format.
        !            25: VAX format workspaces can be converted
        !            26: to PDP-11 format provided they are
        !            27: ``small enough''
        !            28: (if a VAX workspace is too large to
        !            29: be converted to PDP-11 format,
        !            30: it is also too large to run on
        !            31: the PDP-11 APL interpreter).
        !            32: .PP
        !            33: In the usual case,
        !            34: the workspaces to be converted are
        !            35: specified on the command line.
        !            36: The output files have the same names
        !            37: as the input files with a
        !            38: ``.pdp'' or ``.vax'' extension.
        !            39: (If the input file name ends with a
        !            40: ``.pdp'' or ``.vax'' extension,
        !            41: that extension will be stripped off first.)
        !            42: Alternately,
        !            43: .I aplcvt
        !            44: can be used as a filter.
        !            45: (If either the standard input or the standard
        !            46: output are directed to a tty,
        !            47: a syntax message is output.
        !            48: It is highly unlikely that a user will want
        !            49: a converted binary workspace printed on
        !            50: his or her terminal.)
        !            51: .PP
        !            52: The default direction of conversion is
        !            53: to convert to the format used by the host
        !            54: machine;
        !            55: i.e.
        !            56: on a PDP-11 the default is to convert
        !            57: VAX format to PDP-11 format.
        !            58: If desired,
        !            59: the direction may be specified explicitly
        !            60: by a ``\-p'' or ``\-v'' flag.
        !            61: .SH "SEE ALSO"
        !            62: apl(1) \- the APL interpreter
        !            63: .SH BUGS
        !            64: Occasionally,
        !            65: .I aplcvt
        !            66: will bomb out with an error
        !            67: when none really occurred.
        !            68: This seems to be due to a bug
        !            69: in the standard I/O library.
