Unfortunately, you can't allow the first without allowing the second.

I think I can see why one might consider the second form
misleading...but IMHO it's only because the reader would be assuming
what the rest of the SELECT looked like from the first WHEN. I prefer
to look at the code of the entire SELECT before deciding what's going
on.

With good long names and proper usage of constants, I don't
see it as being harder to read.

Consider
SELECT;
WHEN Customer.Type = 'A';
...
WHEN (Customer.Type = 'B'
or Customer.Type = 'C'
or Customer.type = 'D')
and Customer.isTaxable = 'Y'
...
OTHER;
...
ENDSL;

Charles, I don't have a problem with your example. I've also done similar things, but...

Consider
SELECT;
WHEN Customer.Type = 'A';
...
WHEN Customer.isTaxable = 'Y';
...
WHEN (Customer.Type = 'B'
or Customer.Type = 'C'
or Customer.type = 'D')
...
OTHER;
...
ENDSL;

coded this way, I find it misleading.
