>>It wouldn't find what it wasn't supposed to find - which is just what was required. I also first thought this was wrong, but it's actually right. So if neither 6/12 nor 7/12 is between 6/20 and 7/4, good, don't include that period.

>That's true, but I think it's right for the wrong reason. It all depends on what constitutes a pay period, I'd think. BETWEEN wouldn't find it if it was 6/30 to 7/13 either, in which case it would NOT be right that it wasn't found.

Now that IS a good example of when it wouldn't work, because while 7/12 is between these two dates, between(12, 30, 13) will return .f.

So... let me think. Q&D solution:

* try with 12th of the first date's month
d12=date(year(d1), month(d1), 12)
*-- if first date is past 12th, use 12th of the second date
if d12<d1
  d12=date(year(d2), month(d2), 12)
endif
scan for between(d12, d1, d2)
  && do stuff here
