One easy way is to use a math function (sub, add, mult etc.) to have the result set these values on the first scan of the 984. To change the values, you would just need to change the equation to achieve the desired result. I have used this often to keep pre-calculated values "in the program" rather than just stuffing registers which could get over written by accident or erased during a mistake etc. Let me know if you need more info. Good luck!
