NAME
       mset - retrieve ASCII to IBM 3270 keyboard map

SYNOPSIS
       mset

DESCRIPTION
       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  environ‐
       ment  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 termi‐
       nal, 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 alter‐
       nate 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.

FILES
       /etc/map3270        keyboard mapping for known terminals

SEE ALSO
       tn3270(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.
