If you create a dataqueue and simply lets the tiggerpgm add a record with proper data to initiate the computations, file-accesses a.o., your triggered program will not be notably slower. Then create a program which reads the dataqueue, and does the processes needed. This pgm shall then be started as a batch-job.
This designmodel has worked for one of my customers for several years, and they have never had any problems with this second solution for the job. The first solution, was a traditional triggerpgm doing all the lookups etc – at that did’nt work for them.

What file is the trigger program associated with? How is the “moving average” calculated — where do the values come from? Once the calculation is done, where should the “moving average” be stored?
