University of Teesside; Motorola 68000 Assembler and Emulator Page 2 To call X68K the command is: X68K filename OR X68K filename /L (if a listing file is required) where the full name of the file is filename.X68 If the assembly is error-free, a binary output file will be produced with the name "filename.BIN". The mode of the instruction indicates which operand is the source and which is the destination, as well as the operand size. Condition Codes: X — Set the same as the carry bit. N — Set if the result is negative; cleared otherwise. Z — Set if the result is zero; cleared otherwise. V — Set if an overflow is generated; cleared otherwise.
