Whilst feasible (at least under older versions of Stata), your
strategy is ill-advised.

You should document in your do-file all manipulations/edits that are
done to the data, so instead of having -edit if()- statements in your
do-file that bring up the editor and making the changes by hand you
should write statements such as (based on your example...

replace mpg_class = . if(mpg_class == 3 & foreign == 1)

..this way you...

a) document the changes you are making to your data.
b) make your do-file self-contained and your work reprodicible.
c) avoid errors when editing by hand
c) avoid the tedious task of editing data by hand (which is also very boring!)


"... no scientific worker has a fixed level of significance at which
from year to year, and in all circumstances, he rejects hypotheses; he
rather gives his mind to each particular case in the light of his
evidence and his ideas." - Sir Ronald A. Fisher (1956)
