I think the nostop options is useful when when
conducting statstical analyses on final datasets that
have been completely cleaned up, but agree I would not
use it when writing programs or manipulating data. I
think I could use capture for handling the specific
error in most cases, although this slightly more work
than simply typing nostop.

Here is the type of thing example that prompted my
question. I have a series variables named qne1-qne25.


foreach var of varlist qne* {

di in green "`var', categorical water arsenic"
xi: ologit `var' smoke age i.ascat educatio drinking 

test  _Iascat_2= _Iascat_3

predict pone ptwo pthree pfour pfive
gen pbad=ptwo+pthree+pfour+pfive

sort ascat
univar pbad, by(ascat)
drop pbad pone ptwo pthree pfour pfive


}


Now say an error comes up for outcome "qne3" or
something--I am aware of this, but I don't want to
type in manually all of the varnames in the varlist to
account for it. Maybe a different error comes up for
another regression. Some laziness on my part, but
still it is a convenience to be able to use nostop. Of
course I would not want to use it all the time as a
default behavior, but only in certain programs where I
am already aware of the errors.
