avoid the redefinition of a function

Thanks for the answers. I decided to use numbers in the name of the
functions to facilitate function calls. Now if you have this menu
option for instance:

(5) install mc

You can type just "5" as user input and step_5() is called
automatically. If I use descriptive names like install_java() then
selecting a menu point would be more difficult. And I don't want users
to type "java", I want to stick to simple numbers.
