<h1><center>MENU</center></h1>
<hr>
<dl>
<dt>
<b>Function</b>
<dd>
Customizes the textual command menu.
<p>
<dt>
<b>Syntax</b>
<dd>
<tt>MENU option ..;</tt><br>
<tt>MENU;</tt>
<p>
</dl>
<b>See also</b> <a href=28.htm>ASSIGN</a>,
<a href=85.htm>SCRIPT</a>
<p>
The MENU command can be used to create a user specific command menu.
<p>
The complete syntax specification for the <tt>option</tt> parameters is
<pre>
option := command | menu | delimiter
command := text [ ':' text ]
menu := text '{' option [ '|' option ] '}'
delimiter := '---'
</pre>
A menu option can either be a simple command, as in
<pre>
MENU Display Grid;
</pre>
which would set the menu to the commands <tt>Display</tt> and <tt>Grid</tt>;
an aliased command, as in
<pre>
MENU 'MyDisp : Display None Top Bottom Pads Vias;' 'MyGrid : Grid mil 100 lines on;';
</pre>
which would set the menu to show the command aliases <tt>MyDisp</tt> and <tt>MyGrid</tt>
and actually execute the command sequence behind the <tt>':'</tt> of each option when
the respective button is clicked;
or a submenu button as in
<pre>
MENU 'Grid { Fine : Grid inch 0.001; | Coarse : Grid inch 0.1; }';
</pre>
which would define a button labelled <tt>Grid</tt> that, when clicked opens a
submenu with the two options <tt>Fine</tt> and <tt>Coarse</tt>.
<p>
The special option <tt>'---'</tt> can be used to insert a delimiter, which
may be useful for grouping buttons.
<p>
Note that any <i>option</i> that consists of more than a single word, or that
might be interpreted as a command, must be enclosed in single quotes.
If you want to use the MENU command in a script to define a complex menu,
and would like to spread the menu definitions over several lines to make
them more readable, you need to end the lines with a backslash character (<tt>'\'</tt>)
as in
<pre>
MENU 'Grid {\
Fine : Grid inch 0.001; |\
Coarse : Grid inch 0.1;\
}';
</pre>
<p>
<b>Example</b>
<pre>
MENU Move Delete Rotate Route ';' Edit;
</pre>
would create a command menu that contains the commands Move...Route,
the semicolon, and the Edit command.
<p>
The command
<pre>
MENU;
</pre>
switches back to the default menu.
<p>
Note that the ';' entry should always be added
to the menu. It is used to terminate many commands.
