> Compound arguments may be built up from simple ones, using the
|
|
standard +, -, *, and / operators, which carry the usual
|
|
precedence. Also, the unary operators > and <, which
|
|
bind more tightly than anything else, provide the high and low
|
|
bytes of 16-bit values, respectively.

</P

><P
|
|
> Use brackets [ ] instead of parentheses ( ) when grouping
|
|
arithmetic operations, as the parentheses are needed for the
|

indirect addressing modes.
