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. -----Original Message----- From: owner-statalist@hsphsun2.harvard.edu [mailto:owner-statalist@hsphsun2.harvard.edu]On Behalf Of Nick Cox Sent: Tuesday, November 19, 2002 10:36 AM To: statalist@hsphsun2.harvard.edu Subject: st: RE: RE: RE: syntax question David Moore > One problem, > however, is that SAS > allows variable arrays and I believe these still do not > exist in Stata.

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.)
