The Connection menu:

Start
Starts the ROD session. This is usually the first menuitem that you click after running RODGUI. Be aware that the ROD application itself isn't started when you run RODGUI. You have to click on this menuitem to start ROD.


Abort
Aborts and quits the current ROD session. Note that the graphical user interface doesn't quit, just the current ROD session will be terminated.


Load Macro File
A macro file for RODGUI is almost the same as a macro file is for ROD. Users can save a series of commands to a macro file. When clicking on this menuitem, you can load a previous saved macro file (a couple of commands) to the buffer. The macro file doesn't get executed after being loaded!


Save Macro File
Saves the current buffer to a macro file. That means that you save the whole series of commands that you entered via clicking or typing to a data file.


Execute Macro File
Executes the macro file that is currently saved in the buffer.


Show Macro File
Opens a new window that simply presents the current buffer.


Clear Macro File
Empties the buffer.
