I like to have follwing commands directly in the 41OS: (without using the setup menu)
"FILENAM" XEQ "FLSAVE" -> Save the Focal Programm in flash as .RAW
"FILENAM" XEQ "FLLOAD" -> Load FOCAL .RAW from flash to the DM41X memory
"FILENAM" XEQ "FLXSAVE" -> Save the X-Memory to flash
"FILENAM" XEQ "FLXLOAD" -> Load the X-Memory to flash
and for ROM (RAM) pages:
X=<Port> "FILENAM" XEQ "FLRSAVE" -> Save the ROM in Port (X>=8<=15) to flash
X=<Port> "FILENAM" XEQ "FLRLOAD" -> Load the ROM in Port (X) to flash
Thank you for thinking about it...

I like the DM41X very much!! Great Work!
Best regards
Tobie
