Step 1:

     
    You must have these files on your calc.
    Then, at TI-OS home screen, press mylevel().
    To make a new level, just use the 'copy function' of Var-Link.


     
    So you should go to this screen.
    At the right, you can see the list of the graphs.
    At the top-right, you can see the selected graph (Here 'Null' graph).
    You can change it by using + / -
    You can see also a cursor at the top-left : press Left / right / up / down to move it


     
    We will start to work.
    First, we will create a link between a graph and a test.
    Press F1 to enter the menu.
    To choose the graph, you can use Up / down or press a short key : A, B, C
    Here, press 'B' then 'ENTER'.
    Press 'B', not 'b' !


     
    To select the test, you can also use up / down or a short key.
    Here press 'C' and ENTER.


     
    Then you will return to this screen.
    At a corner, press F5 to memorise the coordinates.
    Then press right, right, right, right, right, right.
    And now validate by 'B'.
    Instead of use 'B', you can use '+' / '-' to select the graph in the list,
    and press ENTER to put it at the screen.


     
    Press SPACE to change of mode : graph / test.
    The list has also changed.
    Then go at the cursor position and press F3 :
    You have redefined the starting-point !
    Now, press F2 to test the level .


     
    You play at Fer3c with your level !


     
    Press [2nd] or [Esc] to quit and return editing.
    Press Space to return to Graph mode.
    At a corner, press F5 move to the 2nd corner and press I.
    The item-powers have appeared.
    But there are no test !
    You can't take them, there are just like background !
    Press SPACE to go to test-mode.


     
    At the same corner, press F5, got to the 2nd corner and press 'D'
    or select the test with '+' / '-' and press ENTER.
    Now, the item-powers can be taken !.
    Also, move to a corner and press 'N' to put the end. (Or use the list !)
    You can play your level with 'F2'.
