/*
* This is a Macintosh-to-UNIX interface module. It does the following:
* (1) runs a dialog to obtain the command-line arguments to the UNIX program
* (2) invokes the UNIX program (must change "main" to "UNIX_main")
* (3) displays a scrolling text window for terminal I/O and supports:
* printf
* getchar
* putchar
* exit
*
* Written by: Steven M. Rubin, Apple Computer, 1989.
* Compiles in either LightspeedC or MPW
*

*
* $Log: UNIX.c,v $
* Revision 2.4 91/01/23 11:23:50 malcolm
* Changed initial parameter dialog so strings are shorter (and window isn't
* as wide). Also, changed the pixels per parameter line from 25 to 21. Both
* of these were done so that the dialog would fit on the screen on Macs with
* small screens. Also changed some indentations in the source and made a
* few attempts to get the highlights to be drawn correctly when the program
* starts up (Things like the highlighting of the run button and the boxes
* around the radio boxes aren't drawn now until some other even causes
* ModalDialog to return and force an update.)
*
* Revision 2.3 90/12/18 09:45:22 malcolm
* Added support for Roy Patterson's Model.
*
* Revision 2.1 90/11/06 20:41:50 malcolm
* Miscellaneous Fixes
*
*
* Revision 2.0.1.1 89/07/28 21:38:57 malcolm
* Added taufactor parameter to the command line interface. Also changed
* dialog text boxes so that they would automatically check their check-box
* if their parameters changed.
*
* Revision 2.0 89/07/25 18:56:16 malcolm
* Completely debugged and tested version on the following machines (roughly
* in order of performance):
* Cray, Stellar, SGI, Sun-4, Sequent Balance, Sun-3, VAX, Macintosh under
* both MPW and LightSpeed C.
*
* Revision 1.2 89/07/21 14:37:06 malcolm
* Changed calls to printf to rubin_printf so that LightSpeed C won't have
* to put up a console window.
*
* Revision 1.1 89/07/19 12:31:54 malcolm
* Initial revision
*
*
* The dialog which obtains the command-line arguments is specified by an array of
* strings called "parselist", declared below. The format is as follows:
* parselist := PARAMETERS
* PARAMETERS := PARAMETER
* PARAMETERS := PARAMETER PARAMETERS
* PARAMETER := "[" CHOICES "]"
* PARAMETER := "(" CHOICES ")"
* PARAMETER := "INPUTFILE" [ ":" MACNAME ]
* PARAMETER := "OUTPUTFILE" [ ":" MACNAME ]
* CHOICES := CHOICE
* CHOICES := CHOICE "|" CHOICES
* CHOICE := 'string' [ ":" MACNAME ] [ "ON" ]
* CHOICE := 'string' [ ":" MACNAME ] [ [ "=" ] "INPUTFILE" ]
* CHOICE := 'string' [ ":" MACNAME ] [ [ "=" ] "OUTPUTFILE" ]
* CHOICE := 'string1' [ ":" MACNAME ] [ [ "=" ] 'string2' ]
*
* Less formally, the strings describe a set of parameters to the UNIX program.
* The parameters may be constant strings, choices from a list, input or output
* file names. Optional parameters are surrounded by square brackets. Here are
* some examples:
* (1) The first parameter to a UNIX program is typically the program name. Here,
* a constant string is specified with a quoted parameter (always use single
* quotes) and is optionally followed by a colon and another quoted string that
* will be displayed in the dialog. For example, the UNIX program "test"
* might begin with:
* 'test' : 'My test program'
* (2) A required input file is described with the keyword INPUTFILE, followed by
* the optional Macintosh prompt. For example:
* INPUTFILE : 'Input to the program'
* (3) An optional output file is described with the keyword OUTPUTFILE, and all
* surrounded in square brackets:
* [OUTPUTFILE : 'Output (default is standard output)']
* (4) A list of possible keywords is separated with "|" bars, and enclosed in
* parenthesis or, if they are optional, enclosed in square brackets. For
* example, if the test program can do one-column or two-column output with
* the "-o" and "-t" switches, you might include the following string:
* ( '-o' : 'One column output' | '-t' : 'Two column output' )
* (5) An option may be parameterized if it appears in a required or in an optional
* list. Simply add an additional keyword after the parameter declaration.
* For example, the UNIX option "-t FONT" would be described with:
* [ '-t' : 'Optional font' 'Font Name' ]
* and, if there is no space between the switch and its argument (i.e. if
* the UNIX option is "-tFONT", use an "=" before the parameter keyword:
* [ '-t' : 'Optional font' = 'Font Name' ]
* (6) An option may also take an input or output file name. The UNIX parameter
* "-oFILENAME" would be described with:
* [ '-o' : 'Output File' = OUTPUTFILE ]
* (7) An option may be checked by default. The UNIX parameter
* "-warn" will be generated UNLESS it is checked with:
* [ '-warn' : 'Print warnings' ON ]
