The easiest way is to have the EPDOS.rom installed. Then, on the Exdos.ini file only one command: :START STARTUP.BAS.
Once on the Basic program, we can put a menu to conditionally jump to the selected application with the EXT command.
When re-entering, some check must be done to not load again a new instance of an extension already loaded, for example EGI.rel or Mouse.xr.
