 NAME       : DMSAFT
 Description: bilingual AFT macro
 DSECT      : AFTSECT
 Module Type  Macro
 Function   : Creates a based structure, AFTSECT,
              which names all fields wi thin Active File
              Table Block. AFTSECT describes a file currently
              open for a read or write. The AFT is created
              when a file is opened. Space for up to five
              AFTs is available in DMSNUC; any other must
              reside in free storage.

     The following fields are used for both minidisk AFTs and Shared file
     AFTs.
     When the same areas of storage are used more that once, they are meant
     for different file systems. CDF fields have not been eliminated since
     the code is still in the system, but since it has been disabled, the
     fields have been reused.
