Implementation section hides all the irrelevant innards from other modules, allowing
encapsulation of code.

Everything declared below the keyword 

implements

is private, i.e. has its scope lim-

ited to the file. When you declare an identifier in the implementation section of a
module, you cannot use it outside the module, but you can use it in any block or rou-
tine defined within the module.

By placing the prototype in the interface section of the module (above the 

imple-

ments

) you can make the routine public, i.e. visible outside of module. Prototypes

must exactly match the declarations.
