Is there any tool/software utility that I can use to convert Unix
(v1.0) based application program into Window (WIN98) based oerating
system?

Dear Laformosa,

Thanks for your inquiry.

It looks like there are several sources for the software you seek.
Here are four you can look at:

From AT&T is UWIN:
Http://www.research.att.com/sw/tools/uwin/

From MKS, Inc. Is MKS Toolkit for Enterprise Developers (formerly
NuTCRACKER):
Http://www.datafocus.com/products/tk/ds_tkedev.asp

From Interop Systems, Inc. is:
Http://www.interix.com/

Finally, there is Cygwin by Red Hat, Inc.:
Http://sources.redhat.com/cygwin/

Hope one of these meets your needs.

Google search was: unix windows migration software

Sincerely,

Thanks for your answer. I actually need to convert a C program that
was written in Unix into Windows system. So, besides decompile the
program what else I have to do?

Your request for clarification is sort of getting us into a separate
question of implementation. May I suggest taking a look at the UWIN
FAQ "Development Environment" section (about halfway down this page:
http://www.research.att.com/sw/tools/uwin/faq.html ) for details. If
this doesn't answer all your concerns, I think it might be best to
return to Google Answers with a specific new question to be available
to all GA researchers.

Here's an excerpt from the FAQ mentioned above:

Q 67. What languages does UWIN support? 
A 67. UWIN supports two programming languages, C and C++.  

Q 68. Can I maintain a same Source Base for both UNIX and Windows
versions of my programs?
A 68. Yes. But the programs should confine to XOPEN standards. If the
programs have APIs that are proprietary to a particular flavor of UNIX
then make the appropriate changes to the source to compile on UWIN.

Q 69. Is X11 supported? 
A 69. The X11R6 libraries and fonts have been built for UWIN release
3.1.  The commercial version comes with some X11 client utilities such
as xterm. The X11R6 libraries and fonts have been built with UWIN and
are available as part of the UWIN SDK.

Q 70. Is gcc available for building UWIN executables? 
A 70. The complete GNU compiler set, gcc, g++, g77.exe, gdb is
available for UWIN.

Q 71. Can I run curses programs with UWIN? 
A 71. Yes. UWIN supports vt100 emulation and provides virtually
complete termios support.  The curses library is included in UWIN 3.1.
  

Q 72. Is tcl/tk available for UWIN? 
A 72. UWIN 3.1 supports tcl 7.6. 

Q 73. Does UWIN support sockets? 
A 73. UWIN provides a UNIX interface to WINSOCK (and WINSOCK2 if
installed) and returns file descriptors instead of Windows handles.

Q 74. Can I compile and run C++ applications for UWIN? 
A 74. Yes. UWIN provides the CC compiler that takes the same options
as the compiler on any Unix platform. The compiler is a wrapper over
the underlying native C compiler.

More information needed.  Is this for a document, a Fortran application what?
