Chapter s Operating System 5.1.2 User interface related functions In a sequence of programs, each program is initiated by the user individually. However, the programs are not independent of each other---executing of a program is meaningful only if the previous programs in the sequence execute successfully However, since the programs are initiated individually, their interface with one another is set up explicitly by the user. 在一个程序序列中,每个程序是由用户单独启动的,但程序之 间并非相互独立,只有当前一程序执行成功后,下一个程序的 执行才有意义,但由于程序是独立启动的,它们之间相互的接 口由用户明确设定。 《什第机专出美语 5-24Chapter 5 Operating System 计算机专业英语 5-24 In a sequence of programs, each program is initiated by the user individually.
