Files - Executable
     Executable files are files which are loaded and run
     without further compilation or interpretation.  In
     addition to being manipulated as other file types,
     executable files can be manipulated by the file manager
     and the application manager.
     
     When the file manager/program manager is the active 
     application, double clicking on an executable file 
     will result in this file being executed - run.  
     Likewise selecting the executable file, selecting 
     the File menu option from the menu bar and selecting 
     the Open option will initiate the executable file.  
     Dragging a data file onto an executable file will 
     cause the file manager/program manager to open the 
     executable file with the data file as a parameter.
