OK, I get it. (Way too much time spent on this now.) The sum is also to be

Is this a real business problem or an exercise in whatever?
The original code actually fills a set of buckets with values (or nothing), I
just simplified the code to a loop over an array, changing the values in the
array to do some testing, after first figuring out what was going on.
I don't know the PL/I compiler but on a modern processor Store on Condition
potentially makes
if a(i) >= 0 then switch = 1;
It's more than likely that Enterprise PL/I V5.2 can already generate code that
utilizes new features of the z14 systems.
