Implementation

implementation is a reserved word that is used to structure (subdivide) a unit.

In the implementation section everything that has been declared there can only be used in this unit. It is the private part in other languages.

Example of a unit structure:

 unit ...;      // Name of the unit

 interface      // Everything declared here may be used by this and other units (public)

 uses ...;

   ...

 implementation // The implementation of the requirements for this unit only (private)

 uses ...;

   ...

 initialization // Optional section: variables, data etc initialised here

   ...

 finalization   // Optional section: code executed when the program ends

   ...
 end.
