ABSTRACT:
Method and apparatus for controlling an instrument which can perform a specified cyclic process. The 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.
