[Vim-l] Text editor

[Timothy Bedding]

I am looking for a text editor for Windows which
I can launch using

  editor -ontop file.txt
  editor -ontop file2.txt

to give two Windows, one showing the contents of
file.txt and the other the contents of file2.txt

The -ontop option (or option of similar name)
would cause the windows to be on top.

Is this possible with VIM? If not, is there another
free editor which might permit this?

Regards
Tim
