Michael, thank you again. It works well now. I am now aware of the
usefulness of "capture", which I did not expect to use.
But, like you mentioned, how to fulfill this work in another way, to
check the variable type within the loop? I am very curious at it
because that is the way I meant to do.

You can either check the variable type within the loop or else just use the
capture command:
forvalue i=1(1)614 {
cap encode v`i', gen(vv`i') label(yesno)
if _rc==0 {
drop v`i'
rename vv`i' v`i'
}
}
