Expected 3 arguments after op but got 3

Line 6:
        cmp r3,r0,r0

I miscoded it with three opcodes but the compare just has 2 opcodes.

Not a serious error just an error in the error message since this compiles without error.

    cmp r0,r0

Most of the opcodes in the ALU take 3 args but CMP takes 2. Sorry about the asymmetry.

Checked in C010 with 2 args. You can break it as above ;)

Thank you for your work on this. It's so easy to write code now.
