288 ERROR MESSAGE

When we are requesting: LOCK tablename IN EXCLUSIVE MODE in an ESQL/C program, an -288 error is returned. The -288 error is documented in Informix Error Messages as being returned when an UNLOCK TABLE statement is issued. No mention is made of the -288 error being returned when requesting a LOCK. Does anyone know why Informix OnLine is issuing an UNLOCK error message number when a LOCK is being requested or what additional undocumented meanings this error may have?
