I've updated Beta 2 for the second time, to fix a further problem with capitalised object/room names.

To check if you're running the latest update, start QDK and go to the About window. The latest version is build 4.0.91.

If you're running an earlier build, please download and install Beta 2 again.

1) What exactly is legal in the new style of expressions?

2) How does Quest handle backwards compatability? Is ASL defined so that it only expands, or is the interpreter code filled with "if version < ... do ... else ..."?

Expressions let you use brackets, and the operators + - / and *. They can appear within a "set" command, or within conditions (i.e. within an "if" or "repeat").

Backwards compatibility is handled by checking the game's asl-version tag and running the appropriate code, so yes there are quite a lot of checks throughout the code.

I'd like to get a copy if that's still possible.

Tr0n, I've sent you an email.

I've updated the Beta 2 package yet again because of a similar bug with opening games with capital letters in the room name. Hopefully that's all of them fixed now... the latest build is v4.0.93, so if you're running an earlier build please download Beta 2 again and install.

If you click the "Check for Updates" link on the QDK start screen, you'll be able to easily see if there's a newer version available.
