I know the Octave+Emacs+Windows combination is uncommon. That’s why I
share my experience to the list. I think I found the right place to
post because the help-gnu-emacs list is not Octave-oriented. And my
solution here may be indexed by the search engine with Octave
keywords.

I did what the octave.vbs did in Emacs but still faced the
above-mentioned problem. By now I’m satisfied with my solution.

Thank you,

Chris
