"BS2000 OSD" is a POSIX subsystem on a main frame.

Within the POSIX subsystem, the same character set was chosen as in
"native BS2000", namely EBCDIC. (EDF04)
The name "ASCII" in these routines is misleading: actually, conversion
is not between EBCDIC and ASCII, but EBCDIC(EDF04) and ISO-8859.1;
that means that (western european) national characters are preserved.
This table is identical to the one used by rsh/rcp/ftp and other POSIX tools.
