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

[Nick Cox <njcoxstata@gmail.com>]

I tried this with Windows XP and everything worked.

You should confirm that

1. matwrite.plugin is also copied by -ssc- as a file and put in the
same directory as the .ado and .hlp.

2. Your Windows 7 is 32 bit not 64 bit just in case that is a problem.
