MSET(1)MSET(1)NAMEmset - retrieve ASCII to IBM 3270 keyboard map
SYNOPSISmsetDESCRIPTION
Mset retrieves mapping information for the ASCII keyboard to IBM 3270
terminal special functions. Normally, these mappings are found in
/etc/map3270 (see map3270(5)). This information is used by the tn3270
command (see tn3270(1)).
Mset can be used store the mapping information in the process
environment in order to avoid scanning /etc/map3270 each time tn3270 is
invoked. To do this, place the following command in your .login file:
set noglob; setenv MAP3270 "`mset`"; unset noglob
Mset first determines the user's terminal type from the environment
variable TERM. Normally mset then uses the file /etc/map3270 to find
the keyboard mapping for that terminal. However, if the environment
variable MAP3270 exists and contains the entry for the specified
terminal, 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 terminal 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 terminal type of unknown. If
that search also fails, then a default mapping is used.

SEE ALSOtn3270(1), map3270(5)BUGS
If the entry for the specific terminal exceeds 1024 bytes, csh(1) will
fail to set the environment variable. Mset should probably detect this
case and output the path to the map3270 file instead of the terminal
entry.
