- I need some help to get the callback feature of usersubs going. The problem I
- have is with the stack and stack pointer. How does it work? The documentation
- is quite adamant that I refetch the stack pointer after using the routines
- and I need to know what it is to pass back parameters but I don't understand
- where it comes from, how to get it or how it works (what exactly do sp and st
- do?)
-
- Any enlightenment would be gratefully received.
-
- Dick.
