一、问题的提出我们在DJS-130机上使用RDOS的过程中,曾经发现;当用户要求RDOS对前后台作业并行处理的时候,如果此时用户是同时在后台使用高级语言进行算题,在前台运行由高级语言编写的用户程序,则两者之间就会为使用零页问题发生冲突,产生零页溢出,以致无法同时执行两道作业。鉴于这种情况,就不能同时在后台使用高级语言进行算题,在前台运行由高级语言编写的用户程序,而只能同时在后台使用高级
First, the problem raised We use the RDOS DJS-130 machine in the process, have been found; when the user requests RDOS parallel processing of front and back office operations, if the user at the same time in the background at the same time using high-level language for calculation, in the foreground Run a user program written in high-level language, the two will conflict with the problem of using zero pages, resulting in zero page overflow, so that can not run two jobs at the same time. Given this situation, you can not use high-level language in the background at the same time to solve the problem, run in the foreground user programs written in high-level language, but only in the background while using advanced
