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