Re: st: a question about tempvar

[Jean-Benoit Hardouin <jean-benoit.hardouin@orscentre.org>]

Dear Jian,
__000000 corresponds to the name of the temporary variable `tempxxx'. This "temporary" variable is not dropped in the saved file (only at the end of your command). The solution is to add 
drop `tempxxx'

before the line

save file1.dta, replace
