## ŒNC Name Classification

The monadic system function ŒNC takes a right argument which is a character string specifying a name, or character matrix of names. It returns a numeric result which is the classification of each name:

                1       =         line label
                2       =         variable
                3       =         function
                4       =         operator
                5       =         group
                9       =         class
                0       =         name not in use
               ¯1       =         invalid name

Note: If ŒCS is non-zero, an invalid name may be represented by 4 for compatibility with APL.68000 Level I. See ŒCS for details.
