5.7 Using Subroutines Up ta this point, alf 6f the programs we have seen were contained in a single program area. You can also jump between program areas, so that the reselling execution is made up of pieces in different areas. In such a case, the central program from which other rags aie jumped to is called a “main routine”. The areas jumped to from the main routine are called “subroutines™.
