The keyword begin is used to indicate the start of the executable section of a FUNCTION, method of an OBJECT, PROCEDURE, PROGRAM, property of an object, or is used to delineate the start of a block statement.

For a function, method, procedure, program, or property, it is used after all CONST, TYPE and VAR declarations, and before the first executable statement. It is always terminated by an END statement:

 program Project1;
 var(..);
 begin
   (..);
 end.

For a block statement, it delineates the top of the block, and is also terminated by an END statement:

 if (..)then
 begin
   (..)
 end
 else
 begin
   (..)
 end;

A begin must be closed with end.
