End

The end keyword closes a block of instructions started with the begin or case keyword, ends the declaration of fields of a record, or closes a try .. finally or try .. except construct. It is also used to close a unit having no initialization code.

For example:

 procedure Proc1;
 
 var a,b: integer;
 
 begin
   (..)
 end;

It is also used to end a pascal source file, in which case it is followed by a period rather than a semicolon (in the example below, the last semicolon is optional):

 program Proc2;
 var
   SL: TStrings;
 begin
   SL := TStringlist.Create;
   try
     (..)
   finally
     SL.Free;
   end;
 end.

For a UNIT which contains no initialization, END is used to indicate the end of the unit:

 unit detent;
 uses math;

 procedure delta(r:real);

 implementation

 procedure delta;
 begin

 ...

 end;

 ...

(* Note: No begin statement *)

 end.

Keywords: begin — do — else — end — for — if — repeat — then — until — while
