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

[J Taylor <jwtayl@gmail.com>]

Thank you very much for the help with this. Following Joerg's
suggestion, I did indeed delete all matwrite files manually.
However, I still receive an error:

------------------------------------------
. ssc install matwrite
checking matwrite consistency and verifying not already installed...
installing into c:\ado\plus\...
installation complete.

. clear

. set obs 5000
obs was 0, now 5000

. set seed 1234

. gen x = uniform()

. gen y = 2*x + invnormal(uniform())

. matwrite x y using c:\matlabfile, replace
unrecognized command
r(199);
------------------------------------------

I am running Windows 7.  Ado files can be found on my computer in two locations:
C:\ado
C:\Program Files (x86)\ado

It seems that the base Stata files were installed in C:\Program Files
(x86)\ado, whereas  Updates are installed in C:\ado.  I have installed
user-written commands a good number of times in the past.  I use ssc
install (if it is available) or I copy and paste the ado file into
Notepad, and then save the file as "Filename.ado" in C:\ado\plus\.

Doing some Google searches, I saw it suggested to use the "which"
command to see where the ado file is being called from (perhaps this
speaks to Daniel's suggestion about matwrite not being on the path or
not having read/write privileges)
http://www.stata.com/support/faqs/lang/adopath.html

. which matwrite
c:\ado\plus\m\matwrite.ado
*! matwrite version 0.90, 15/12/04, (c) Andrew Shephard
. which regress
C:\Program Files (x86)\ado\updates\r\regress.ado
*! version 1.2.7  02oct2009
. which reg_ress
command reg_ress not found as either built-in or ado-file
r(111);

This is perhaps a rather mundane question, but does anyone have a
sense of why I am still experiencing these problems?  Did I rule out
the suggestion about matwrite not being on the path or not having
read/write privileges through the "which" commands above?

Thanks,
JT
