I was reading the DM guide for fun and to get a better idea of other details, and I happened to come across something interesting. Chapter 11, section 2.5: ftp output, and 2.6: run file output. And it got me thinking,

Is there a way to update the game DURING runtime?

Best response
No, DM is a compiled language and as such there is no support for updating the game and having that update reflect during that current runtime.

However, it is possible to build your own interpreted language on top of DM and run all your logic through that, because those languages are interpreted at runtime. If you took such a course then yes, you could update the game at runtime within some sort of scope defined by the complexity of your interpreted language.
hmm. Alright. Thank you!
