I would guess Algol doen NOT force you to use BEGIN-END. Simula does
definitely not do it, and as far I know Algol is a true subset of
Simula.

In Algol W, a program is a statement (see the BNF), so beginning programmers
often see programs like

	for i:= 10 to 100 by 5 do
		write(i, " degrees C = ", 1.8 * i + 32.0, " degrees F").

In Algol 68, if memory serves, a particular-program is a unit, so one should
be able to do similar things.  Same goes for procedure bodies, so to show the
halting problem is insoluble, one can write (perhaps prepending "Behold!" as
was done for a famous proof of the Pythagorean theorem :-)

	proc paradox void:
		while halts(paradox) do skip od
