Run-time problem

P59 - You can't implicitly repeat through the values of this kind

Most problems are detected when Inform translates the source text, but this is one of the exceptions, a "run-time problem" which emerges only during play.

With some kinds of value, like scenes, you can easily repeat through all possibilities at run-time: there are only a small number of them, and their values are easy to work out and put into a sensible order. With others, either there are too many (this is why repeating through numbers or texts can't be done) or they have no sensible order (this is why repeating through rules can't be done). You can see which kinds can be repeated through on the Kinds index page.

Inform tries to catch this mistake when translating the source text if possible, but sometimes it isn't possible, and this problem message is the result.
