 NAME       : DMSAFT
 DESCRIPTION: bilingual AFT macro
 DSECT      : AFTSECT
  odule 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.
