Loops
repeat
looping-statement
until boolean-expression
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.
