[next] [prev] [prev-tail] [tail] [up]

#### public

The Public keyword is used to declare a function globally in a unit. This is useful if the function should not be accessible from the unit file (i.e. another unit/program using the unit doesn’t see the function), but must be accessible from the object file. as an example:

     Unit someunit;
     interface
     Function First : Real;
     Implementation
     Function First : Real;
     begin
       First := 0;
     end;
     Function Second : Real; [Public];
     begin
       Second := 1;
     end;
     end.

If another program or unit uses this unit, it will not be able to use the function Second, since it isn’t declared in the interface part. However, it will be possible to access the function Second at the assembly-language level, by using it’s mangled name (see the Programmers guide).
