49 | .Sh DESCRIPTION | |
50 | .Nm Mset | |
51 | retrieves mapping information | |
52 | for the | |
53 | .Tn ASCII | |
54 | keyboard to | |
55 | .Tn IBM | |
56 | 3270 terminal | |
57 | special functions. | |
58 | Normally, these mappings are found | |
59 | in | |
60 | .Pa /usr/share/misc/map3270 | |
61 | (see | |
62 | .Xr map3270 5 ) . | |
63 | This information is used by the | |
64 | .Xr tn3270 | |
65 | command (see | |
66 | .Xr tn3270 1 ) . | |
67 | .Pp | |
68 | The default | |
69 | .Nm mset | |
70 | output can be used to store the mapping information in the process environment | |
71 | in order to avoid scanning | |
72 | .Nm map3270 | |
73 | each time | |
74 | .Nm tn3270 | |
75 | is invoked. | |
76 | To do this, place the following command in your | |
77 | .Pa .login | |
78 | file: | |
79 | .Bd -literal -offset indent | |
80 | set noglob; setenv MAP3270 "\(gamset\(ga"; unset noglob | |
81 | .Ed | |
82 | .Pp | |
83 | If the | |
84 | .Ar keyboardname | |
85 | argument is not supplied, | |
86 | .Nm mset | |
87 | attempts to determine the name of the keyboard the user is using, | |
88 | by checking the | |
89 | .Ev KEYBD | |
90 | environment variable. | |
91 | If the | |
92 | .Ev KEYBD | |
93 | environment variable is not set, then | |
94 | .Nm mset | |
95 | uses the user's terminal type from the environment variable | |
96 | .Ev TERM | |
97 | as the keyboard name. | |
98 | Normally, | |
99 | .Nm mset | |
100 | then uses the file | |
101 | .Xr map3270 5 | |
102 | to find the keyboard mapping for that terminal. | |
103 | However, if the environment variable | |
104 | .Ev MAP3270 | |
105 | exists and contains the entry for the specified keyboard, then that | |
106 | definition is used. | |
107 | If the value of | |
108 | .Ev MAP3270 | |
109 | begins with a slash (`/') then it is assumed to be the full pathname | |
110 | of an alternate mapping file and that file is searched first. | |
111 | In any case, if the mapping for the keyboard is not found in | |
112 | the environment, nor in an alternate map file, nor in the standard map file, | |
113 | then the same search is performed for an entry for a keyboard with the name | |
114 | .Ar unknown . | |
115 | If that search also fails, | |
116 | then a default mapping | |
117 | is used. | |
118 | .Pp | |
119 | The arguments to | |
120 | .Nm mset | |
121 | are: | |
122 | .Pp | |
123 | .Bl -tag -width Fl | |
124 | .It Fl picky | |
125 | When processing the various | |
126 | .Pa map3270 | |
127 | entries (for the user's keyboard, | |
128 | and all those encountered before the one for the user's keyboard), | |
129 | .Nm mset | |
130 | normally will not complain about entries for unknown functions (like | |
131 | .Dq PFX1 ; | |
132 | the | |
133 | .Fl picky | |
134 | argument causes | |
135 | .Nm mset | |
136 | to issue warning messages about these unknown entries. | |
137 | .It Fl shell | |
138 | If the | |
139 | .Pa map3270 | |
140 | entry is longer than the shell's 1024 environmental variable | |
141 | length limit, the default | |
142 | .Nm mset | |
143 | output cannot be used to store the mapping information in the process | |
144 | environment to avoid scanning | |
145 | .Pa map3270 | |
146 | each time | |
147 | .Nm tn3270 | |
148 | is invoked. | |
149 | The | |
150 | .Fl shell | |
151 | argument causes | |
152 | .Nm mset | |
153 | to generate shell commands to set the environmental variables | |
154 | .Ev MAP3270 , | |
155 | .Ev MAP3270A , | |
156 | and so on, breaking up the entry to fit within the shell environmental | |
157 | variable length limit. | |
158 | To set these variables, place the following command in your | |
159 | .Pa .login | |
160 | file: | |
161 | .Bd -literal -offset indent | |
162 | mset -shell > tmp ; source tmp ; /bin/rm tmp | |

164 | .It Ar keyboardname | |
165 | When searching for the | |
166 | .Pa map3270 | |
167 | entry that matches the user's keyboard, | |
168 | .Nm mset | |
169 | will use | |
170 | .Ar keyboardname | |
171 | instead of determining the keyboard name from the | |
172 | .Ev KEYBD | |
173 | or | |
174 | .Ev TERM | |
175 | environmental variables. | |
