Thanks for all the help. Walt Eric Booth wrote:

Assuming you've already got this dataset in memory: ** clear inp A1 A2 1 2 2 3 3 4 5 6 end ** You could use -input- : ** inp str25 brand"Cheerios""Wheaties""Frosted""other" end ** ~ Eric __ Eric A.

Let me try again. Here's the data: A1 A2 1.35 -2.48 1.50 0.56 0.75 -1.2 ... I want to add a third variable, brand, that has nothing to do with the specific numbers for A1 and A2, but rather with the rows. So, I want A1 A2 brand 1.35 -2.48 Cheerios 1.50 0.56 Wheaties 0.75 -1.2 Frosted ... A1 and A2 come from an MDS estimation by converting the e(Y) matrix to variables. I now need to add the brands for further processing. It seems I should be able to do something like gen str brand = "Cheerios" "Wheaties" "Frosted" etc But it doesn't work, unless I just mistyped something. Hope this helps clarify what I need. I really appreciate the help.
