I would like to obtain summary statistics (by another variable) for a list
of 100 variables, and then save all of these in one big matrix, and
preferably have this exported into a text file.

I have been following the discussion surrounding -tabstatmat-as well as that
regarding the command - mat2txt-  (Feb 2004)  but running mat2txt on my
computer gives me the error message: "version 8.2 not supported" (I use
Stata 8) and with tabstatmat I don't know if I can do this repeatedly. For
example, writing a tiny program such as the one below does not seem to work:

foreach X of varist v1-v100 {
    quietly tabstat `X', statistics(mean, sd) by(category_`X') save
    tabstatmat mat`X'
    svmat mat`X'
    keep mat`X'*
    dropmiss, obs
    outsheet using c:\data\matrix.txt
}

Do you happen to know what I can do so that all the results from each
tabstat on each variable are appended together in one big matrix?

Thank you in anticipation.
