In BASIC the GOSUB command will go to a bookmark thing (or in other forms of BASIC a numberline) adn then do the proccesses there and then continue a long until it hits the return command then it will go back to where you issued the GOSUB command and then it will continue from there. The purpose of ti is so that instead of having to make a version of the section of code for every place you need it.
