  19     "BS2000 OSD" is a POSIX subsystem on a main frame.
  20     It is made by Siemens AG, Germany, for their BS2000 mainframe machines.
  21     Within the POSIX subsystem, the same character set was chosen as in
  22     "native BS2000", namely EBCDIC. (EDF04)
  23
  24     The name "ASCII" in these routines is misleading: actually, conversion
  25     is not between EBCDIC and ASCII, but EBCDIC(EDF04) and ISO-8859.1;
  26     that means that (western european) national characters are preserved.
  27
  28     This table is identical to the one used by rsh/rcp/ftp and other POSIX tools.
