Adding new rows

[Esteban Jara]

Hello. As a result of a dofile, I obtained a .dta database with 4 variables (x1, x2, x2, and x4) and 1000 rows. Within that same dofile, I need to manually add 3 more rows of data at the end of the database, with arbitrary values for x1, x2, x2, and x4 (and without adding any new variables). How can I do this? Thanks.
