mankrip, for my comments about precedence in #24 I was looking at the vanilla Quake source code. I don't use DarkPlaces.
In
Cmd_ExecuteString() in cmd.c, the first word of the command line is checked first against function commands, then aliases, then cvars. So it looks like aliases would override cvars even in vanilla Quake. They certainly do in QuakeSpasm 0.93.1, in which Cmd_ExecuteString() looks essentially unchanged. Unless I'm overlooking something?
