* --- codedata.do
use dataset
... some manipulations
do uglycoding
save myfile
* --- end codedata.do
* --- uglycoding.do
forval ...
tempvar ...
... calculations ...
}
* --- end uglycoding.do
Then the coding all gets done with a single call to -codedata.do-, which
calls -uglycoding.do-. The tempvars are then local to uglycoding.do,
and are automatically dropped when it ends, allowing -codedata.do- to
resume, and to save a clean dataset.

They were dropped automatically, but you could not benefit from it. Entertain this: -- tempvar_example.do -- sysuse auto, clear tempvar one gen byte `one' = 1 save auto_one, replace exit -- end of tempvar_example.do -- At the completion of tempvar_example.do, you won't see any tempvars (although -describe- would indicate that the file has actually changed). But the saved version will contain whatever was present at that spot in time, including the ugly named __000000 or whatever the available -tempvar- name will be. So -capture drop __00*- may often be a good idea (you want -capture- just in case that there was no temp crap left, otherwise -drop- would produce an error).

There were a load of temporary variables created in the process of making my "voldat.dta" data set. But I had simply assumed that they would have all disappeared when the data creation do file had successfully completed. And they it turns out that they hadn't. They weren't in my face as "voldat.dta" is large. The (non-elegant) code which creates the tempvars is: quietly { forval t = 1/18 { forval f = 0/1 { tempvar temp1 tempvar temp2 tempvar temp3 tempvar temp4 regress mwage1 A A2 A3 A4 if mwage1 > 0 & !missing(mwage1) & wave == `t' & female == `f' predict double `temp1' if e(sample), residuals regress mwage1 A A2 A3 A4 [aw = xrwght] if mwage1 > 0 & !missing(mwage1) & wave == `t' & female == `f' predict double `temp2' if e(sample), residuals regress mwage2 A A2 A3 A4 if mwage2 > 0 & !missing(mwage2) & wave == `t' & female == `f' predict double `temp3' if e(sample), residuals regress mwage2 A A2 A3 A4 [aw = xrwght] if mwage2 > 0 & !missing(mwage2) & wave == `t' & female == `f' predict double `temp4' if e(sample), residuals replace mwage1res_u = `temp1' if mwage1 > 0 & !missing(mwage1) & wave == `t' & female == `f' replace mwage1res_w = `temp2' if mwage1 > 0 & !missing(mwage1) & wave == `t' & female == `f' replace mwage2res_u = `temp3' if mwage2 > 0 & !missing(mwage2) & wave == `t' & female == `f' replace mwage2res_w = `temp4' if mwage2 > 0 & !missing(mwage2) & wave == `t' & female == `f' } } } I've now added a -drop __*- line after this section, and the temporary variables are no longer retained in "voldat.dta". And the job with the call to -idonepsu- now works again. I remain surprised that the tempvars weren't automatically deleted at the end of the data creation job. ------------------------------------------------------------------------ -------- From Stas Kolenikov <skolenik@gmail.com> To statalist@hsphsun2.harvard.edu Subject Re: st: r(110) error with -svy-, -mark-, -marksample- Date Tue, 31 Jul 2012 17:19:23 -0500 ------------------------------------------------------------------------ -------- 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.

The puzzle is that I have no problems with similar commands applied to data from the Ref Manuals (cf. example below: uses "stage5a.dta").
