I am exporting a toolsheet that connects to a Kmax server.  Kmax requires the server IP address to be entered in the device pane, but this cannot be edited in the runnable.  The problem is that I don't know the server address in advance.  How can I set the server address in a Kmax runnable after it is exported ?

Just leave the field blank.  When the runnable is executed the user will be prompted for the server address.
