Dear All,
I have a do-file called hem.do which I would like to run. But before I
run this do-file I need to drop some observations if dov >= d(1jan90).
Hence
use data, clear
drop if dov >= d(1jan90)
do hem.do
keep if id==5
save newdata1, replace
I would like to repeat this process about a thousand times with
different dates and ids located in a separate file (SEE SNIPPET) then
post to a single file. For example,
use data, clear
drop if dov >= d(2feb90)
do hem.do
keep if id==5
save newdata2, replace
use newdata1, clear
forvalues i=2/1000 {
append using newdata`i'
}
SNIPPET
id date_of_onset
5 1jan90
5 2feb90
5 6jun96
7 10oct97
7 25dec99
Can this be done?
Raphael
