.Sh DESCRIPTION
|
|
.Nm Mset
|
|
retrieves mapping information
|
|
for the
|
|
.Tn ASCII
|
|
keyboard to
|
|
.Tn IBM
|
|
3270 terminal
|
|
special functions.
|
|
Normally, these mappings are found
|
|
in
|
|
.Pa /usr/share/misc/map3270
|
|
(see
|
|
.Xr map3270 5 ) .
|
|
This information is used by the
|
|
.Xr tn3270
|
|
command (see
|
|
.Xr tn3270 1 ) .
|
|
.Pp
|
|
The default
|
|
.Nm
|
|
output can be used to store the mapping information in the process environment
|
|
in order to avoid scanning
|
|
.Nm map3270
|
|
each time
|
|
.Nm tn3270
|
|
is invoked.
|
|
To do this, place the following command in your
|
|
.Pa .login
|
|
file:
|
|
.Bd -literal -offset indent
|
|
set noglob; setenv MAP3270 "\(gamset\(ga"; unset noglob
|
|
.Ed
|
|
.Pp
|
|
If the
|
|
.Ar keyboardname
|
|
argument is not supplied,
|
|
.Nm
|
|
attempts to determine the name of the keyboard the user is using,
|
|
by checking the
|
|
.Ev KEYBD
|
|
environment variable.
|
|
If the
|
|
.Ev KEYBD
|
|
environment variable is not set, then
|
|
.Nm
|
|
uses the user's terminal type from the environment variable
|
|
.Ev TERM
|
|
as the keyboard name.
|
|
Normally,
|
|
.Nm
|
|
then uses the file
|
|
.Xr map3270 5
|
|
to find the keyboard mapping for that terminal.
|
|
However, if the environment variable
|
|
.Ev MAP3270
|
|
exists and contains the entry for the specified keyboard, then that
|
|
definition is used.
|
|
If the value of
|
|
.Ev 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
|
|
.Ar unknown .
|
|
If that search also fails,
|
|
then a default mapping
|
|
is used.
|
|
.Pp
|
|
The arguments to
|
|
.Nm
|
|
are:
|
|
.Pp
|
|
.Bl -tag -width Fl
|
|
.It Fl picky
|
|
When processing the various
|
|
.Pa map3270
|
|
entries (for the user's keyboard,
|
|
and all those encountered before the one for the user's keyboard),
|
|
.Nm
|
|
normally will not complain about entries for unknown functions (like
|
|
.Dq PFX1 ;
|
|
the
|
|
.Fl picky
|
|
argument causes
|
|
.Nm
|
|
to issue warning messages about these unknown entries.
|
|
.It Fl shell
|
|
If the
|
|
.Pa map3270
|
|
entry is longer than the shell's 1024 environment variable
|
|
length limit, the default
|
|
.Nm
|
|
output cannot be used to store the mapping information in the process
|
|
environment to avoid scanning
|
|
.Pa map3270
|
|
each time
|
|
.Nm tn3270
|
|
is invoked.
|
|
The
|
|
.Fl shell
|
|
argument causes
|
|
.Nm
|
|
to generate shell commands to set the environment variables
|
|
.Ev MAP3270 ,
|
|
.Ev 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
|
|
.Pa .login
|
|
file:
|
|
.Bd -literal -offset indent
|
|
mset -shell > tmp ; source tmp ; /bin/rm tmp
|
|
.Ed
|
|
.It Ar keyboardname
|
|
When searching for the
|
|
.Pa map3270
|
|
entry that matches the user's keyboard,
|
|
.Nm
|
|
will use
|
|
.Ar keyboardname
|
|
instead of determining the keyboard name from the
|
|
.Ev KEYBD
|
|
or
|
|
.Ev TERM
|
|
environment variables.
