There's at least one thing you can do with the SAS macro programming
language that I have found useful. You can create functions. I know egen
allows some limited capabilities with respect to new variable generation,
but functions are more general. For example, they can be used to calculate
or return values in many different programming contexts, not just to create
variables.

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.)
