I'll help! First, to make code, go into the "EDIT" mode on the bottom of the touch screen.
Now, you can start. Here are some simple things to start.
CLS- clears text on screen
ACLS- clears EVERYTHING on screen
PRINT-prints text on screen [ex:PRINT "Hello!"]
WAIT- Pauses the program until the amount [ex: WAIT 60] (60 is equivalent to 1 second)
@LABEL- Used to create loops or main menus (the label can be named what ever you want, such as @MAIN or @loop)
BUTTON()- an action will occur if a certain button will be pressed. [ex: IF BUTTON() AND #A then goto @main]
