mset - retrieve ASCII to IBM 3270 keyboard map
mset [-picky] [-shell] [keyboardname]
Mset retrieves mapping information for the ASCII keyboard to
IBM 3270
terminal special functions. Normally, these mappings are
found in
/usr/share/misc/map3270 (see map3270(5)). This information
is used by
the tn3270 command (see tn3270(1)).
The default mset output can be used to store the mapping information in
the process environment in order to avoid scanning map3270
each time
tn3270 is invoked. To do this, place the following command
in your
.login file:
set noglob; setenv MAP3270 "`mset`"; unset noglob
If the keyboardname argument is not supplied, mset attempts
to determine
the name of the keyboard the user is using, by checking the
KEYBD environment
variable. If the KEYBD environment variable is not
set, then
mset uses the user's terminal type from the environment
variable TERM as
the keyboard name. Normally, mset then uses the file
map3270(5) to find
the keyboard mapping for that terminal. However, if the environment
variable MAP3270 exists and contains the entry for the specified keyboard,
then that definition is used. If the value of
MAP3270 begins with
a slash (`/') then it is assumed to be the full pathname of
an alternate
mapping file and that file is searched first. In any case,
if the mapping
for the keyboard is not found in the environment, nor
in an alternate
map file, nor in the standard map file, then the same
search is performed
for an entry for a keyboard with the name unknown.
If that search
also fails, then a default mapping is used.
The arguments to mset are:
-picky When processing the various map3270 entries (for
the user's
keyboard, and all those encountered before the
one for the
user's keyboard), mset normally will not complain about entries
for unknown functions (like ``PFX1''); the
-picky argument
causes mset to issue warning messages about
these unknown
entries.
-shell If the map3270 entry is longer than the shell's
1024 environment
variable length limit, the default mset
output cannot be
used to store the mapping information in the
process environment
to avoid scanning map3270 each time tn3270
is invoked.
The -shell argument causes mset to generate
shell commands to
set the environment variables MAP3270, MAP3270A,
and so on,
breaking up the entry to fit within the shell
environment
variable length limit. To set these variables,
place the
following command in your .login file:
mset -shell > tmp ; source tmp ; /bin/rm
tmp
keyboardname
When searching for the map3270 entry that matches the user's
keyboard, mset will use keyboardname instead of
determining
the keyboard name from the KEYBD or TERM environment variables.

The mset command appeared in 4.3BSD.
