23 "BS2000 OSD" is a POSIX on a main frame. It is made by Siemens AG, Germany.
24 Within the POSIX subsystem, the same character set was chosen as in
25 "native BS2000", namely EBCDIC.
27 EBCDIC Table. (Yes, in EBCDIC, the letters 'a'..'z' are not contiguous!)
28 This apr_table_t is bijective, i.e. there are no ambiguous or duplicate characters

83 /* This apr_table_t is (almost) identical to the previous one. The only difference
84 * is the fact that it maps every EBCDIC *except 0x0A* to its ASCII
85 * equivalent. The reason for this apr_table_t is simple: Throughout the
86 * server, protocol strings are used in the form
87 * "Content-Type: text/plain\015\012". Now all the characters in the string
88 * are stored as EBCDIC, only the semantics of \012 is completely
89 * different from LF (look it up in the apr_table_t above). \015 happens to be
90 * mapped to \015 anyway, so there's no special case for it.
92 * In THIS table, EBCDIC-\012 is mapped to ASCII-\012.
93 * This apr_table_t is therefore used wherever an EBCDIC to ASCII conversion is
94 * needed in the server.
