Too few arguments to macro "OOPOBJ"

[aleksblendwerk]

Getting this when trying to compile it on W32:

routines\h\demo.h:21: INPUT_ERROR: Too few arguments to macro "OOPOBJ".

Might be just me, I haven't worked with WLA before. I am particularly interested in checking out the music replayer's output (sound), basically I'd even be fine with just a pre-compiled binary right now. Thought I'd file this anyway though.
