This is occurring in annotations/where_clause_post2.rules. Looks like we need to add rowid (and recid) into the vartypes map. I think this means we need similar changes to the exptypes map above it. Note that classes RowidExpression and RecidExpression do not currently exist.

Is there any case for RECID I can use?
For ROWID I testedn the changes with something like FIND FIRST book WHERE TO-ROWID(book.price) = ROWID(customer) NO-LOCK NO-ERROR.
but for RECID there is no equivalent to TO-ROWID

Costin, use this test:

function func0 returns recid(buffer bb for book). end.
find first book where func0(book.book-id) = recid(book).

I'm reviewing this now.

Beside the header in RecidExpression (where you reference RowidExpression), I don't see any problems. I'm putting this into conversion regression testing on my system.

Conversion regression testing has passed, please check in and distribute update.
