.TH FONTEDIT 1 LOCAL
|
|
.SH NAME
|
|
fontedit \- Edit fonts.
|
|
.SH SYNOPSIS
|
|
.B fontedit file
|
|
.SH DESCRIPTION
|
|
.I Fontedit
|
|
is used to edit the down line reloadable character set (DRCS) of a VT220
|
|
terminal. The editor has two display areas, one for displaying the
|
|
entry currently being manipulated, and one for displaying the complete
|
|
DRCS. Commands to the editor take the form of function keys.
|
|
.PP
|
|
.I Fontedit
|
|
takes one command line parameter, a file name. This file is
|
|
used to save the character set. If the file exists when \fIfontedit\fP
|
|
is invoked, it is read in to initialize the DRCS. The file is written
|
|
to when \fIfontedit\fP exits.
|
|
.PP
|
|
Commands to fontedit take the form of function keys. The current
|
|
definitions are:

|
|
Display a help screen.
|
|
.IP \fBF6\fP
|
|

|

|
|
.PP

|
|
.PP
|
|
To exit \fIfontedit\fP, press <control-D>. The DRCS will be saved in

\fIfile\fP. To exit without saving the DRCS, hit interrupt (usually
|
|
DEL).
|
|
.SH DIAGNOSTICS
|
|
.I Fontedit
|
|
will issue a warning when the entry being worked on is not saved, and
|
|
some potentially destructive command, like \fBSelect\fP is used. To
|
|
override the warning message, immediately reissue the command.
