Yes, the "right quote" is bogus, even though you are hitting the correct key.

A likely explanation is you are using an editor that has the feature called "smart quotes".
"Smart quotes" converts typewriter ' and " to the typeset versions, ' and ".

Solution: turn it off or use a different editor.

Subject: st: help! Strange error in Stata

This code (within a do-file)

. sum year
. local minyear = r(min)
. local maxyear = r(max)
. local yrdiff = `maxyear' - `minyear' // T-1

Generates the following result (and error):

Variable | Obs Mean Std. Dev. Min Max
year | 2244 1979.5 12.70126 1958 2001
`maxyear' invalid name

When I type the same code on the command line, I don't get the error --
however, when I erase and retype the code within the do-file, I get the
same error. I am running Stata/SE 9. I really have no idea what is going
on. I have scrutinized for spelling, etc. The code that I sent was
copied out of the do-file directly. I do wonder about the right single
quote (it looks funny), but I am using Stata's do-file editor, and am
using the single-quote-key directly to the left of the "enter" key. Can
anyone help?
