Zandronum

I can't tell whether this is me being dumb or this not being in Zandro, but Zandronum won't run the example of A_SetAngle on the Zdoom Wiki. This looks like to me that the function isn't included in Zandronum, but this function dates back to 2009... and I have no idea what version or when Skulltag got behind ZDoom.
Is there any way for me to check what functions Zandronum does/doesn't have? (Like specifically where in the sourcecode I would look, if possible.)

There are so many more like this, if you knew you'd be amazed...

I already guessed as much, which is why I would LOVE to have a list of included functions...

by now, the differences between zandronum decorate and zdoom decorate are so large, it'd fill a magazine

so don't expect anyone to come with a list - I'd only do it if I were paid
