Anyways...
Assuming a clean & accurate &PARTFILES& (often not a good assumption, and here's where it costs you a little something), you can use that to determine how many parts there are currently. The more accurate way is to query the dist file header (IIRC, it's an mv attribute returned by SYSTEM). If that's wrong, you can get sloppy & execute a LIST.DF CAPTURING to parse out.
So, for each part, execute a phantom which reads the part, does the evaluation, & writes to an &SAVEDLISTS& item, perhaps one named for the part. Then you can just either write another short program to merge them, or do it in the editor. The trick is to make sure that you wait until the individual lists are finished building.

Hopefully Dan F can add more, and provide better information than I am able to
remember.
There was some claims processing programs that utilized this, or some
similar technique where the nbr of threads, or nbr of program instances, would
be passed in to a driver program, and that would split up the processing by
spawning that number of phantoms. Back at that time there may have been
something around 40 parts. I don't remember if it was based on the nbr of part
files or if there was an algorithm that split up the record keys into a
designated instance nbr.
