Pop-Up Menus and 0-Symbols
            
            A "0-symbol" is a symbol that does not have a data mask in a P+ID. As no data is available from a data mask, it is not simple to assign a 0-symbol to a pop-up menu button. Proceed as follows:
- Load the Symbol Library containing the 0-symbol.
 - Create an icon from the symbol
 - Open a P+ID and select the Load symbol option from the context menu and then the Symbol pop-up menu option. Next select the pop-up menu to which the 0-symbol should be assigned.
 - Click the button to which the symbol should be assigned. When the cross-hairs appear, press the right mouse button to call the context menu and select the Edit button assignment option.
 - Next, select the icon file and symbol as described in the previous section, and enter the appropriate auxiliary text.
