    • An instru­ment's process is controlled by a computer which has two concurrently defined tasks: an operator task for running an instrument control program, and a compiler task for compiling new instrument control programs input by the instrument's user. The currently running program is suspended and a new program's execution is begun when (a) a new program has been successfully compiled by the compiler, and (b) the current program is about to perform a jump back at the end of an instruction loop. When a main instrument control program finishes execut­ing, a new program is run if a new program has been successfully compiled; otherwise, execution of the most recently suspended program resumes. Thus a newly compiled program interrupts the currently running program only between instruction loops, and only as long as necessary to execute its instructions. If the newly compiled program merely resets a parameter, this inter­ruption is generally so short as to be unnoticeable. If, on the other hand, the newly compiled program is designed to control the instrument's process for a period of time, the new program takes control until it finishes execution. Thus the instrument's user is provided not only with the feel of being able to reset parameter values on the fly, but also with a flexible tool for revising an instrument control program on the fly.
    • 仪器的过程由具有两个同时定义的任务的计算机控制:用于运行仪器控制程序的操作员任务以及用于编译仪器用户输入的新仪器控制程序的编译任务。 当(a)编译器成功编译了一个新程序,并且(b)当前程序即将在指令循环结束时执行跳转,当前正在运行的程序被暂停并且开始执行新的程序。 当主仪表控制程序完成执行时,如果新程序已成功编译,则运行新程序; 否则,恢复最近暂停的程序的执行。 因此,新编译的程序仅在指令循环之间中断当前正在运行的程序,并且只要执行其指令就可以。 如果新编译的程序仅仅重置一个参数,则这种中断通常很短,不能引人注目。 另一方面,如果新编译的程序被设计为在一段时间内控制仪器的过程,那么新的程序将被控制,直到完成执行。 因此,仪器的用户不仅具有能够即时重置参数值的感觉,还提供了一个用于修改仪器控制程序的灵活工具。
