; Test file for 4502 extended opcode compliance
; This odd little source file uses every addressing mode
; of every opcode, and uses the opcode itself as the argument
; to each instruction that takes one. The resulting binary's
; bytes are thus in strictly increasing numerical order.
; Some opcodes have multiple mnemonics; we provide both.
; This file also doesn't include the 4502's opcodes that
; are also available in stock 6502s - see testbase.oph for
; those. However, it does include those extensions share
