That's painful to look at.
Isn't it more efficient to do the select and then read the id's while they are in

What if your selection contains 500,000 items, won't that IDS array be huge ?

For any of the newbies on this forum, there are a few things to mention
about READNEXT.
First, it is not married to or dependent upon LOOP...REPEAT. That's just one
of the popular ways it's used. I've seen and used it in different
structures.
Second, the dynamics of WHILE/UNTIL behave
