Mitchell Sent: Dienstag, 8. Juni 2010 22:32 To: statalist@hsphsun2.harvard.edu Subject: Re: st: QUestion using -fs- package Dear Nuno I think you are 99% of the way there. I think the problem is that the variable -file- needs to be a string variable, thus you might try this.... qui fs *.dta foreach f in `r(files)' { use `f', clear cap drop file gen str50 file="`f'" save, replace } Two other thoughts... 1) the -save , replace- is a pretty scary command. If you make a bad mistake you could destroy the original file. So, when doing something experimental like this, it is prudent to have a solid backup of all the data files. 2) You (or someone else) might be interested in putting a -note- in the data file (rather than a variable). If you wanted to do that, you could change the -gen- command to be note : This comes from the `f' data file I hope that helps, Michael N.
