Does ecmarkup support something like break;?

Or in order to do this:

1. Let _found_ be *null*.
2. For each Record _x_ of _y_, do
   1. If ..., then
      1. Set _found_ to _x_.
      2. Break.

Do I have to manually iterate over y?

1. Let _found_ be *null*.
2. Let _len_ be the length of _y_.
3. Let _i_ be 0.
4. Let _stop_ be *false*.
2. While _i_ < _len_ and _stop_ is *false*, do
   1. If ..., then
      1. Set _found_ to _x_.
      2. Set _stop_ to *true*.
   2. Set _i_ to _i_ + 1.

1. Let _wrapperList_ be a List of the same length with _y_ whose each element _O_ is ! OrdinaryObjectCreate(*null*, « [[WrappedSpecValue]] ») and _O_.[[WrappedSpecValue]] has been set to the coresponding value in _y_ in _y_'s order.
2. Let _finder_ be a new Abstract Closure with parameters (_currentValue_) that captures ... and performs the following steps when called:
    1. If ..., then
        1. Return *true*.
    2. Return *false*.
3. Let _finderF_ be CreateBuiltinFunction(_finder_, 1, "", « »).
4. Let _foundResult_ be ! Call(%Array.prototype.find%, ! CreateArrayFromList(_wrapperList_), « _finderF_ »).
5. If _foundResult_ is *undefined*, then
    1. ...
6. Let _matched_ be _foundResult_.[[WrappedSpecValue]].

Just a joke LOL

nicolo-ribaudo: it does not support break. easiest thing in your case is probably

1. Let _found_ be *null*.
1. For each Record _x_ of _y_, do
   1. If _found_ is *null* and ..., then
      1. Set _found_ to _x_.
