I did 2/4 stages of the compiler. The thing is that some preprocessor flags have to stay after the preprocessor is done. Here are they:
$protect on/off //Compiler pus jumps on vars.
$filter on/off //See example
$filter on
Ret5():
retb 5;
Ret6():
retb 6;
$filter off
start():
db five=Retb5();
On compilation, the compiler won't include Ret6() because it ain't used
