CP and SUB are very much like ADD, SBC, ADC, etc. However, there is a difference: CP and SUB can only be performed on A, while the others can also be performed on (at least) HL.

For this reason, according to my documentation, the first argument should not be specified for CP and SUB. So the correct way of writing it would be
CP 002h
which is assembled correctly.

However, the assembler should at least emit a warning about the junk at end of line which was not parsed. Perhaps it would be a good idea to also allow this alternative notation.

CP A, 002h should compile to: FE 02, but instead compiles to BF, which is the opcode for CP A, A.
