Back to Reserved words.

The reserved word interface is used to structure (subdivide) a unit. This is distinct from the Interfaces facility.

Everything that has been declared in the interface section can be used by this and other units. It is the public 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.
