I don't know what your first paragraph, about leaving off the length,
refers to, but I don't think it means decalare the comparison field with
no length.

You haven't declared a length for the field &FPRDN, so the system
defaults it to 32 bytes.  This is standard behaviour for CL..  I presume
that the INCREL is then failing because the fields are different
lengths, although this surprises me somewhat.  I'd expect it to fail if
they were different data types, but not just different lengths.

Try defining &FPRDN as 15 bytes and see what happens.

Cheers,

Martin.
