Re: st: r(110) error with -svy-, -mark-, -marksample- |

The most obvious explanation is that you do have that __000003 variable present in your data set, for some strange reason (the data set was saved while -tempvar- was created, but before it was cleaned with an exit from a program). Sometimes, I do get something like that with a complicated set of nested routines and some complicated patterns of who creates and who cleans the -tempvar-s, although I would expect that Stata would try to come up with the next available -tempvar- name upon having checked that a variable already exists in the data set. The conflict like that may also arise if you deliberately drop a tempvar rather than let Stata do it. But it would be strange if this error were in the official code.
