Thanks, Roger, Nick Both suggestions work, but something like . local bull = "count if char(96)tempchar(39) >0" . `bull' unknown function () r(133); does not work. . local lq = char(96) . local rq = char(39) . local bull = "count if `lq'temp`rq' >0" . `bull' 334 (works) . local bull "count if \`temp\' >0" . `bull' 334 (works) Nick - I see a legitimate need for this when you have a long expression involving temporary variables or names that may make the code look ugly if written out next to some other long statement.

Use \` to insert a literal left quote if the urge is overwhelming. 2. Better, resist the urge. Rewrite your code so that you don't need to do it. This came up a few months ago, but I can't find my post. Martin Weiss will probably remember it. Nick n.j.cox@durham.ac.uk Feiveson, Alan H. (JSC-SK311) Can someone please tell me how to define a local macro that contains literal single quotes? For example Suppose I want to do something like local bull "count if `temp' > 0" where `temp' is to be interpreted literally, not evaluated. * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/ * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
