Sometimes it is necessary to delete a program, for example to free it for a completely different program. If the program is empty, this function (Delete button) is not available. After pressing the button  (Delete) a red button to confirm the operation will appear instead of program information in the right part of the screen.

 

 

The button gradually disappears and after about 5 seconds it disappears and the program information appears again. If the button is pressed during these 5 seconds, the selected program will be deleted. The program can also be deleted by writing the command End in the first block of the program. The deleted program becomes empty (yellow font).
