Repeat … Until

repeat and until repeat the lines between them. After each round the condition of until is tested: when it is true the loop ends, otherwise it starts again from repeat. The lines therefore always run at least once, unlike a while loop, which tests its condition before the first round.

The condition is true only when it evaluates to #true, which is -1. Comparisons (=, <, in, …) produce -1 or 0, and &&, || and ! combine those as expected. A plain value is not turned into true or false: if 1 and if yes are both false, and if %flag is true only when %flag holds #true. See #True and #False.

Braces between repeat and until are optional; they only make the loop easier to read. Loops can be nested: each until belongs to the nearest repeat before it that is not already taken.

Leave the loop early with break, or skip to the test with continue.

Example

set %str Hello , #spc , World
repeat
  set %str %str , !
  str len %str
until #StrRes >= 30
display ok %str
halt

The ! is added and str len runs once before #StrRes >= 30 is tested for the first time.
