methods, select one of them. Upper case letters and the symbols #, !, $ and [ ] are keywords and must be written as
they are. Each symbol has the following meaning.

• $: Relative address specification
• [ ]: Indirect address specification
In the case of immediate data, describe an appropriate numeric value or a label. When using a label, be sure to
For operand register identifiers r and rp, either function names (X, A, C, etc.) or absolute names (names in
