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!)
