Run-Time Problem
This use of '[text]' is too complicated (P64)
    

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.


The '[text]' token in Inform's grammar for 'Understand' has limitations.It has to be followed by a fixed wording, or be at the end of the line, inorder to match. If you're seeing this as a run-time problem, you've probablydone something cunningly indirect, but you've run into the problem all thesame.
