1 There is lots of examples of and / or here look at code by Tharwat he uses this method a lot.
2 Jump ? You can call defuns in the middle of code and return to next line etc I know did it for a bubble sort routine needed a left and right option choice.
3 look into ssadd.
4 look at ssget filters there are lots "X" come to mind.
