Implementation section hides all irrelevant innards from other units, allowing encap-
sulation of code.

Everything declared below the keyword 

implementation

is private, i.e. has its

scope limited to the file. When you declare an identifier in the implementation sec-
tion of a unit, you cannot use it outside the unit, but you can use it in any block or
routine defined within the unit.

By placing the prototype in the interface section of the unit (above the implementa-
tion) you can make the routine public, i.e. visible outside of unit. Prototypes must
match the declarations exactly.
