I want my computer programs prompt the message "waiting for the current jobs end and quit the processes." "quit the processes, when current works finished" "interrupt the current process when the current jobs finished" What is the best expression, or any other expression. Those are the expression of an error or cann't understand. It sounds as though you are asking for the best wording of three different prompt messages. If I am accurately understanding what you wish to convey, the first should say: Wait for the current jobs to end and then quit the processes or programs. The second would mean the same thing and I would word it: Quit the processes when the current work is finished. The final message seems to indicate something different. You seem to be suggesting that the user might be doing something else on the computer and that what they are in the process of doing should be interrupted once the current jobs completed running. If so, then it should state: Interrupt the current process when the current jobs are finished. If you think I misunderstood what you were asking, feel free to message me and I will see if we can't work out a better answer for you.
