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

126 * is the fact that it maps every EBCDIC *except 0x0A* to its ASCII
127 * equivalent. The reason for this apr_table_t is simple: Throughout the
128 * server, protocol strings are used in the form
129 * "Content-Type: text/plain\015\012". Now all the characters in the string
130 * are stored as EBCDIC, only the semantics of \012 is completely
131 * different from LF (look it up in the apr_table_t above). \015 happens to be
132 * mapped to \015 anyway, so there's no special case for it.
134 * In THIS table, EBCDIC-\012 is mapped to ASCII-\012.
135 * This apr_table_t is therefore used wherever an EBCDIC to ASCII conversion is
136 * needed in the server.
