+.TH termput "" "" "/rdb Command"
+.PC "Get terminal capability from /etc/termcap file"
+\fBtermput \fIcapability\fR
+.PP
+.II termcap
+.II "terminal^get capability"
+The command
+.B termput
+reads and returns the current capabilities for your terminal, as set in file
+.BR /etc/termcap .
+A two-letter capability code is followed by a string of characters
+that, when sent to the terminal screen, turn on or off that capability.
+This assumes, of course, that your terminal is properly described in
+.BR /etc/termcap .
+.SH Capabilities
+The capabilities are two-letter codes recognized by
+.BR termcap .
+Here are some examples:
+.DS
+\fBcl\fR	Clear the terminal screen
+\fBcm\fR	Cursor movement
+\fBso\fR	Start standout mode (e.g., reverse video)
+\fBse\fR	End standout mode
+.DE
+.PP
+Using most of these codes is straightforward:
+just echo the appropriate code to the terminal to get the effect you want.
+Cursor movement, however, is more complicated;
+the cursor-movement code that
+.B termput
+returns must be edited to hold
+the row and column to which you wish to move the cursor.
+For details,
+see the manual page for the command
+.BR cursor .
+.SH Example
+You can embed
+.B termput
+in a shell script to
+help invoke reverse video, blinking, and any other
+your terminal has defined in
+.BR /etc/termcap .
+.PP
+The first example clears the screen:
+.DM
+	termput cl
+.DE
+.PP
+The next example puts the screen into reverse video:
+.DM
+	termput se
+.DE
+.PP
+and the following turns off reverse video:
+.DM
+	termput so
+.DE
+.PP
+You can use
+.B termput
+to initialize environmental variables, which you can then invoke
+in a shell script.
+This is much faster than making repeated calls to
+.BR termput .
+To set up these shell variables, insert the following commands
+your file
+.BR  $HOME/.profile :
+.DM
+.ta 2.5i
+export AE=`termput ae`	# end alternate character set - graphics
+export AS=`termput as`	# start alternate character set - graphics
+.DE
+.DM
+.ta 2.5i
+export CLEAR=`termput cl`	# clear the screen
+export CURSOR=`termput cm`	# cursor movement - for the cursor command
+export MB=`termput mb`	# start blinking mode
+export ME=`termput me`	# turn off all attributes
+export SE=`termput se`	# end stand out mode
+export SO=`termput so`	# start stand out mode
+export UE=`termput ue`	# end underline mode
+export US=`termput us`	# start underline mode
+.DE
+.PP
+Once this is set up, you can use these environmental variables in your
+shell program.
+For example, if you want a message to stand out, bracket it with
+.B $SO
+and
+.BR $SE :
+.DM
+	echo "${SO} LOGOFF NOW ${SE}"
