Language and Character Map Within a Session
A preferred language and a character map are associated with every TRANSFER
session. The TRANSFER delivery system uses the language and character map to
process requests within the session. Once a session is underway, you cannot alter its
language or character map.
For sessions initiated with the START-SESSION UOW, language and character sets are
determined according to the contents of the VERSION-CODE field of the header for
the current IPC:
TRANSFER versions prior to B40 set the language to English and the character
map to US ASCII.
B40 and later versions of the TRANSFER delivery system use the language and
character map specified by the system default values in the SYSTEM-LANG-
CMAP-ID configuration entity. Since no session is available before the START-
SESSION UOW is issued, the TRANSFER delivery system assumes that the
CORR-NAME, PASSWORD, and CURR-LOCAL-TIME fields are in the native
form defined by the local node's default character map. (Note that within a
TRANSFER system, the default language and character map can vary on different
nodes.)
The START-SESSION-B40 UOW allows you to specify the preferred language and
character set.
B40 and later versions of the TRANSFER delivery system perform the following steps
before comparing the password in the PASSWORD field with the password stored on the
system:
1. The TRANSFER delivery system translates each native character into the
equivalent character in the configured base character set.
2. The TRANSFER delivery system translates any character that does not have an
equivalent in the base character set into the error character for that set. (The base
character set always contains one error character, and this is the character used as
a substitute whenever normal mapping fails.)
A password stored in the system is also translated in this same way prior to storage.
Therefore, any nongraphic characters in the submitted password equate to control
characters appearing in the same sequence in the stored password.
The TRANSFER delivery system returns RESOLVED-NAME in native form.
