I just would like to thank Kit, Brent and Nick for the valuable help and
comments on my question. Both approaches have worked nicely here and I am
currently running my analyses without problem.

Thank you for your time.



Dear Statalisters,

I have the following do file (and a lot of .dta files):

set obs 100
tempname M
forvalues i = 1/100 {
forvalues u = 1(0.1)1.6  {
	use "C:\TEST\RR=`u'_replication_number_`i'.dta"
	set more off
	quietly summarize A
	matrix `M' = nullmat(`M') \ ( r(mean),  r(N))
svmat double `M' , name(results)

-svmat- saves results as:

results1 results2
1.2 56
1.3 85

Nonetheless, I would like to add to the matrix a third collumm, which will
have the name of the .dta file. For example,

results1 results2 results3
1.2 56 RR=1.2_replication_number_1.dta
1.3 85 RR=1.2_replication_number_2.dta

Is this difficult to do without changing much my simple do file? I have
tried the vecdiag option, unsuccessfully, however.

I will be very grateful for any help again.
