14.3 Function results

The result of a function can be set by setting the result variable: this can be the function identifier or, (only in ObjFPC or Delphi mode) the special Result identifier:

Function MyFunction : Integer;  
 
begin  
  MyFunction:=12; // Return 12  
end;

In Delphi or ObjFPC mode, the above can also be coded as:

Function MyFunction : Integer;  
 
begin  
  Result:=12;  
end;

As an extension to Delphi syntax, the ObjFPC mode also supports a special extension of the Exit procedure:

Function MyFunction : Integer;  
 
begin  
  Exit(12);  
end;

The Exit call sets the result of the function and jumps to the final End of the function declaration block. It can be seen as the equivalent of the C return instruction.
