The string, delimited by quotes or apostrophes, is scanned for a substring which selects which instruction set is used. When the program is invoked, this operation is performed on the name of the program, then the -p optional argument, if any, and then any CPU statements. The last one selects which subset of the instructions the assembler will accept. The instruction set can be changed at any place in the source file.

CPU6801 The instruction is only valid for the 6801 instruction set. TS6801PLUS The instruction is valid for the 6801 and 68hc11. TS6811 The instruction is only valid for the 68hc11 instruction set. REGA The instruction can use the A accumulator. REGB The instruction can use the B accumulator. REGX The instruction can use the X index register. REGY The instruction can use the Y index register. DIRECT The instruction can use the direct addressing mode. The expression must have a value between 0 and 255 that is defined when the instruction is processed in the input pass. EXTENDED The instruction can use the extended addressing mode. A.2.3 Notes A.2.3.1 Apostrophes The apostrophes in the syntax field are a notation used for the parser generator and are not put in the assembler source statements. - 16 - A.2.3.2 Indexed_Addressing The indexed addressing is represented in two ways. Either "expression, index register" or "index register, expression" is accepted by the assembler. Index register is X for all instruction sets and X or Y for the 6811.
