Nick has correctly guessed the Stata idiom for converting most of the illustrated SAS programming constructs. One problem, however, is that SAS allows variable arrays and I believe these still do not exist in Stata. You can program around this, of course, but that's not a simple matter of converting from one language to another. Those with Stata 7 will benefit from the "new" looping commands. Those of us who still can't afford to upgrade must resort to -while- loops. -----Original Message----- From: owner-statalist@hsphsun2.harvard.edu [mailto:owner-statalist@hsphsun2.harvard.edu]On Behalf Of Nick Cox Sent: Tuesday, November 19, 2002 5:40 AM To: statalist@hsphsun2.harvard.edu Subject: st: RE: syntax question angelach@u.washington.edu > > Hi Stata users, I'm now trying to convert SAS language to > Stata.

Or more seriously, I don't know SAS, so I am guessing. do seems to map to -forvalues-. There is a tutorial on -forvalues- -- for which you need to know the rudiments of local macros -- at http://www.stata.com/support/meeting/8uk/fortitude.pdf EQ presumably is a test for equality so that is ==. The main pitfall to be aware is the difference in Stata between the -if- command and the -if- qualifier.
