* Hexadecimal number constants should be used except where decimal or binary numbers make much more sense in that constant's context.
* Hexadecimal letters should be upper-case.
* When you set two registers or two memory locations to an immediate 16-bit zero, you should use the expressions ```#<$0000``` and ```#>$0000``` (they make it obvious where you are putting the lower and upper bytes).
* If a function is declared to return a char-sized value, it actually must return an integer-sized value. (When cc65 promotes a returned value, it sometimes assumes that the value already is an integer.)
* If a function is declared to return a char-sized value, it actually must return an integer-sized value. (When cc65 promotes a returned value, it sometimes assumes that the value already is an integer.) This must be done in one of the following ways:
<pre>
lda #RETURN_VALUE
ldx #0 ; return value is char
</pre>
or, if the value is 0, you can use:
<pre>
lda #RETURN_VALUE
.assert RETURN_VALUE = 0
tax
</pre>
sometimes jumping to return0 could save a byte:
<pre>
.assert RETURN_VALUE = 0
jmp return 0
</pre>
* Functions, that are intended for a platform's system library, should be optimized as much as possible.
* Sometimes, there must be a trade-off between size and speed. If you think that a library function won't be used often, then you should make it small. Otherwise, you should make it fast.
* Comments that are put on the right side of instructions must be aligned (start in the same character columns).
