Am I missing something, or does xlfTextref from the C API not support
named ranges?

If I have a (possibly disjoint) range of cells named myRange, then the
Excel 4 macro command
=TEXTREF("myRange")
returns the range named by myRange, but the C command
Excel4(xlfTextref, &xArgRef, 1, TempStr(" myRange"));
returns xlretFailed.
