(One way of doing it)

:-) This will be my fifth Adventuron-powered game, so I've used a fair amount of this stuff before... or pestered Chris to tell me how to do a lot of this stuff before.

There's code like that in the Scout's Honour example code, linked to in the sticky post. It has some interesting examples in it, but I wouldn't code an Adventuron game like that these days as it doesn't really make good use of a lot of Adventuron's strengths and special features... I was basically coding like I would've done on a Spectrum with PAWs... so I did a lot of stuff with booleans, where I'd now do them a lot simpler with Adventuron's own checks like has_not_created. (I'm not 100% sure that was even in Adventuron when I first wrote the game)

Control + Space will almost always work on a new line, but yes, not if there is a serious syntax error (like a missing } or ;).

If Control + Space does not work, try pressing Control + S (Save) first, to see if there is a serious syntax error.

As far as a master list of commands, no, there is not that right now, but I hear the call, and I'll try to put something together.

There was (and is) a reason why a lot of commands are omitted. set_string is obscured because I don't think it is required for simple adventure games.

It's a slippery slope really when you start down the path of what's useful to intermediate users. I think that a lot of people here are moving way beyond the simple use-cases and into intermediate / advanced use cases.

I did have a separate version of Adventuron planned for that, without the "classroom" monikor. 

I will reveal set_string to the autocomplete in the next release, but I believe "add" has always been there, from day one of classroom. I certainly added "append" to the list of revealed commands.

• // Use expression form to calculate an integer result
• // Floating point not supported by Adventuron, only integer mathematics
• // The statement below sets c to be the value of "a" multiplied by the value of "b"

 : set_integer var = "c"  {(a * b)}
