In the example of code you have, the loop will exit if your key
(variable ID) is equal to an empty string or a string that can be
evaluated to zero for example values like

As for the loop structure, I tend to like this:
SELECT FILENAME
LOOP WHILE READNEXT ID
CODE
CODE
CODE with GOSUB
CODE
CODE
REPEAT
It's clean, it's concise, it's easy to read... And I wish I could
remember who taught me

Regarding your loop structure below. What happens if the ID is empty

It shouldn't, at least not to a empty ID because the
condition test is on the READNEXT, not the ID.
However, it will pass an empty ID to the coding

Nope. It's running off of an active select list, it'll process the
record. Since I'm selecting
I never thought about a ID. Is this something you would do
deliberately for some reason or is it something that would happen
accidently? Can you write a record with a null ID? What would it hash
to?

I thought this was a safe way to check for the end of the list. I just
used the ID as a flag and I wasn't sure what the value would be at the end
of a list. I guess I was assuming that a SELECT list would not

We have found out the hard way that an unintentional empty string record
ID can also produce some VERY strange record lock situations. It seems
like everyone who tries to access the file winds up queued for a record
lock on the bad ID. (UD/SB+/Prelude)

If, as stated in another response to this thread, the poster doesn't
want the record that has a null-id to be processed, then I'd probably do
something like
If the ID equates to false it will exit - i.e. a record with ID 00
