Prototype
ERRCODE recno(
AREAP wa,
ITEM record
)

identifier, and will normally be a number indicating the row number.

cursor position for use by the CA-Clipper runtime system. If your driver
operates on a database that does not contain record numbers, you must
provide a unique value to be used to identify each row.

subclass.
Implementation Notes
. If your RDD supports relations, update them with a forceRel()
prior to attempting relative movement.
