Thats a Minus..... Tja that's the problem with Unix - minimal service and no inteligence providet :) To support a solution like above, The OS must be aware of the user at all time and special keycodes have to be reserved for the OS. Personaly I also prefere more inteligent OSes - BS2000 for example offers the same functionality. Press the K2 key and the programm is interupted and the OS prompt comes up - get information, even start orther tasks - use any OS command needed (maybe without loading a new programm into your task, since this will destroy the old :). And because the debugger is just a set of OS commands, you're free to poke around ... Sigh. Brave old world :) Gruss H. -- Ich denke, also bin ich, also gut HRK
