Glulx Input Loops
version 1/101121 by Erik Temple
Chapter - Debugging command (for use with Extended Debugging by Erik Temple)
[The debug command itself is probably useless for most situations, since by the time it runs we will have exited both from the secondary loop where it was entered and from main input as well. Still, it is provided for completeness. The more effective route will be to deploy a simple say phrase from source code; that is, use the phrase 'say "[currently running input loops]"' at the appropriate point in your source code.]
Understand "loops" or "input loops" as a mistake ("[line break][currently running input loops]").
