Put -capture- in front of any command that should not abort with an error.

Subject: st: no observation in while-loop
Hello,
I have a panel with 148 countries (id) over 30 years (time).
I need fitted values for one of the variables therefore I created this
while loop
local i=1
while `i'<=148 {
use DataBase.dta
keep if id==`i'
reg machines import
predict machfilled
save A`i'
local i=`i'+1
}
However, for some countries, there is no data available and the loop
stops. Then Stata returns "no observations".
Is there a way to skip these countries without observations? So that the
loop will not be interrupted.
Thank for your help
