Begin

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.
