[XeTeX] Using XeTeX

[rm2kpro at gmail.com]

Hello.
I’m running Windows XP (32-bit) and I installed the MikTeX distribution. 
I looked for
an editor which supports Unicode and I chose WinShell.
I can perfectly compile documents using pdflatex, but xelatex doesn’t 
want to work for
me. I defined a ‘user program’ in WinShell, entered the path for xelatex 
and I put the
following in the command line: ‘-src-specials -interaction=nonstopmode 
“%s.tex”’.
When I run it, it gives this output:

This is XeTeX, Version 3.141592-2.2-0.997 (MiKTeX 2.7)
entering extended mode

What should I do? Do you recommend me another editor?
