Once a Menu File has been selected it can be loaded by by clicking the Load Menu button in the Control Panel. This does four things. It loads the selected menu, it pops up the first menu page in that menu, if the menu has within in a application identified which can be executed once the menu options are defined, it adds up to three RUN buttons to the Control Menu, and it lists all of the defined menu pages associated with the loaded menu in the Menu Page List Boxes at the bottom of the Control Panel.
An example Control Panel after loading a Menu might look like
A Loaded Menu File can be saved at anytime by clicking on the Save Menu file. This writes the current copy of the loaded menu down to the file name indicated in the Save To field in the Control Panel. If the loaded menu was selected through the Find Menu option then the saved menu name will be written to the selected Save Directory and will have appropriate extension appended to it.
Manually entered Menu Files will have an extension added only if it was or is present in the designated Save To file name.
If the loaded menu is tied to an application, then the Run BkGnd and the Run FrGnd buttons will appear on the Control Panel. In some cases the Run TkWin may also appear. Once the menu options have been filled in clicking Run FrGnd will launch the application. This saves the current menu state to the Save To file then runs the application in the foreground with the Save To filename as a command line entry. When running in the foreground the menus are frozen until the application stops.
Clicking the Run BkGnd button has the same effect as clicking the Run FrGnd button has except that the application is run in background. This makes the menus accessible when the application is running for further modification.
If the application contains graphical output the Run TkWin button will appear. This should be used to launch the application if the graphics options have been set up to select the use of the TK Canvas graphics driver. All output from the application is piped to a Tk Window where it is interpreted and plotted.
