I put a question several days back on how to share data between UNIX
user program and a commercial spreadsheet.  Here is the summary of
what I got so far.  Thank you for those who responded to my question.

And I devided possible solutions into four categories:

          Spreadsheet    User data               Location
       ____________________________________________________________________
       1   on Mac/PC      Excel(native) format     on Unix file system?
       2   on Mac/PC      SYLK  format             on Unix file system?
       3   PC-emulator    Excel(native) format     on emulator file system?
       4   on Unix        Excel(native) format     on Unix

Jess Holle recommends to check WingZ from Informix:
 "I would contact Informix, the maker of WingZ.  Among other things,
 "they have a Real-Time data link package, though I'm not sure if it 
 "is needed for what you are doing.
 "
 "WingZ does do SYLK output.
 "
 "WingZ is reasonably Excel-like and runs on over a dozen platforms (or
 "is it just a dozen).  SOME of those platforms are: OS/2, MS-Windows,
 "Macintosh, Sun (Open Windows and Motif), Apollo, SGI, NeXT,.... that's
 "all I can remember at the moment.

Everette Allen also recommends to check WingZ.

Robert Sum recommends to check various Unix spreadsheets:
 "  I do not have complete information, but I think that you should investigate
 "some of the Unix spreadsheets--especially if your data is already on Unix.  I
 "know that Lotus, Xess, Aster*x, and (I think) Wingz all run on Unix.  Lotus,
 "Aster*x, and Wingz all have well developed macro languages.  Aster*x includes
 "support for Unix socket communication. Xess does everything using RPC.  I
 "think
 "that Xess and Aster*x are relatively cheap.  (In the case of Aster*x, their
 "complete product line that includes a word processor, spreadsheet, graphics
 "package, electronic mail front end, file filters, etc. is only about
 "$2K.  I'm sure that the spreadsheet alone is probably well under that.)
 "
 "  There are also public domain spreadsheets available for UNIX.  Sc and
 "Oleo are
 "both available through the GNU folks at prep.ai.mit.edu.  I do not know much
 "about their features, but with the source you can do anything, right?  I have
 "also heard mention of Xspread, but I do not know anything about it.

Joel Spolsky told me that the book for the Excel 4.0 format is available:
 "The file format of Excel 4.0 is included in an MS-Press book
 "entitled "Microsoft Excel Software Development Kit". This should
 "be available from Penguin in Japan.
 "
 "It is usually easier to write the file in CSV (comma separated values)
 "format, which Excel can easily import from the usual "File/Open" command.

Clifford Matthews told me about two Mac-emulator for NeXT:
 "We make "Executor", a Macintosh emulator for the NeXT.  I can run  
 "Excel 4.0 for the Mac.  The reason this makes more sense than SoftPC  
 "is both Macs and NeXTs share the same CPU, which means that Executor  
 "on a NeXT doesn't have to emulate the underlying CPU; hence it's  
 "fast.
 "
 "Another possibility might come from our competitor, Athena Design.   
 "They currently have a SpreadSheet called "Mesa".  It has a well  
 "defined API that may be of use to you.  I also believe they are  
 "currently working on Excel file compatibility.

Mike Kienenberger also recommends to check with Executor.

In summary, running a spreadsheet application on Unix is a popular
solution than I'd thought.  I checked the listed price of WingZ in
Japan (available from ASCII).  They are, 98,000 yen for Mac, OS/2,
and MS-Windows 3.0, 168,000 yen for single user license on Sun,
Sony NEWS and HP, and 128,000 yen each for additional user.
(Academic discount will be available.)

For option 3 (running spreadsheet on PC/Mac-emulator), I had no answer
on pros and cons of sharing file system between the emulator and Unix.

I'm personally interested in Option 1, since we are developing the
data acquisition software ourselves.  Maybe the MS-press book would tell
me the answer...

Thanks again to those who have contributed.
