Stata does not have arrays as such. But see the FAQ
http://www.stata.com/support/faqs/data/arrays.html
(which predates Stata 7) and add to it the facilities of -foreach- and
-forvalues- and then the question -- for those
who know both SAS and Stata -- is what can
be done easily or with a little effort in SAS
which is difficult or impossible in Stata? (The reverse
question might interest some people, of course, but is not
mine.)
