Thanks. To the last comment, I am using odbc to get the varnames. I decided not putting in the question to be concise. I was actually trying to avoid 'if' somethng like we do for integers i.e. [firm(int -1)] . I had done something like this prior to posting. At least, the way you suggested makes my code shorter. syntax, [firm(str)] if "`stat'"!="" { graph pie varname, by(varname) plabel(_all `stat') } else { graph pie varname, bu(varname) plabel(_all percent) } Thanks, Tashi ---------------------------------------- > Date: Tue, 25 Sep 2012 15:12:18 +0100 > Subject: Re: st: have string macro default in syntax > From: njcoxstata@gmail.com > To: statalist@hsphsun2.harvard.edu > > This is easy; just not easy with -syntax- alone. > > Note that this discussion is one where the distinction between syntax > in general and the command -syntax- helps clarity considerably.
