    functions through existing interfaces:

    o  Support for a wider range of characters in a file name,
       extension, and directory

    o  Access to file specifications with extended characters

    o  Support for directory structures deeper than eight levels

    o  Access to file specifications longer than 255 bytes through
       the NAM block with some restrictions in functionality

    o  Access and complete specification of file specifications
       longer than 255 bytes by callers who are aware of the new
       naming characteristics through a new interface (NAML block)
