How about, for "execute at least once":

REPEAT:
	code
	WHILE condition

REPEAT:
	code
	UNTIL condition

DO doesn't imply repition and only seems to have appeared to help parsers find the start of a block.

If the WHILE/UNTIL clause is missing, the loop must be terminated by a BREAK or other means.

Furthermore, while we're on the subject, I prefer:

WHILE condition:
	code
	REPEAT

UNTIL condition:
	code
	REPEAT

Python-like syntax with the colon at the start of a block avoids the ambiguity you might otherwise
produce with the same keyword being used at the start or end of a loop.

The REPEAT clause could be optional here so the WHILE is as in Python now. 

I think WHILE and UNTIL should always both be available.

WHILE 1 is ugly and implies that a pointless test being made - although one hopes this is optimised
out.

As for a name, how about Monty? If you later produce an expanded syntax you could call that the Full
Monty.
