(Of course, LCALLs in my first example are a little bit stupid...) And, this scheme works, until the table is not dynamic (in RAM of any kind/EEPROM etc.) And for longer tables it is inefficient. But all these schemes don't answer the original question (although it has been already answered) - if an inidrect jump routine is called from multiple positions and it should return to from where it has been called (= an indirect call), the "indirector" should be called rather than written inline to the code. Although, nothing wrong nor dangerous is with pushing the return address onto the stack, it's just inefficient in every respect. Jan Waclawek |
