Re: st: Problem Using Matwrite, "unrecognized command" error

[Nick Cox <njcoxstata@gmail.com>]

-ssc install- should install the .plugin but it did not do so. Why was
that? I don't know, but typing

. ssc copy matwrite.win32

in the same directory also worked for me. I am out of ideas otherwise
on why this still doesn't work.
