I think of ` ' as meaning "evaluate this here and now". Here should be obvious, but the now is important too, meaning precisely "before you try to execute this command line". `macname' is the canonical example for local macro macname. But `= 2 + 2' `c(date)' `r(varlist)' `e(cmdline)' `: value label foreign' are other examples in which you also want literal text substituted. I don't know if this is ever official wording -- indeed I doubt it -- but I think of examples other than the first as invoking the local macro persona of beasts that are not local macros in the most restricted sense but can behave similarly given persuasive syntax. Nick n.j.cox@durham.ac.uk Michael I. Lichter I understand that single quotes are not simply local macro dereference operators, but it certainly looks like that's their function in the command line. Other than local macro, what can you dereference in this way? * * 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/
