A preferred language and a character map are associated with every TRANSFER
session. The values for these parameters are specified by the START-SESSION-B40
UOW that initiates the session. The TRANSFER delivery system uses these values,
together with the value in the VERSION-CODE field of the IPC header, to determine
what language and character map to use in processing requests within the session. If
these fields are set to 0, the default values apply 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-B40 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 character map requested in CHAR-MAP-ID or selected by
default. (Note that within a TRANSFER system, the default language and
character map can vary on different nodes.)
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.
