Loops

repeat

repeat
looping-statement
until boolean-expression

The NewtonScript repeat loop is very similar to repeat loops in other languages:

e := q:Entry();
repeat
   :Foo();
   e := q:Next();
until e = nil;
The repeat loop evaluates its boolean expression at the bottom of the loop. If the expression is nil, it jumps back up to the repeat. If the expression is non-nil, it skips to the next statement. The looping statement is always executed at least once.
