Sorry, i forgot to explain ...
"?" is a treasure.
"?" is a monster (perhaps a knight... i had to find a good story to print on the tape inlay !!!!)
and "?" is a sword.

"£" is the player...

12 LET X=1
13 LET Y=1
14 LET G=0
15 LET S=0
16 LET M=0
Should be:
12 LET X=PI/PI
13 LET Y=X
14 LET G=TAN PI
15 LET S=G
16 LET M=S
It's now a perfect tutorial !!!
Without any D_File stuff !!! ... dedicated to Crayon21.
TAN PI = ("Tant pis" in French) ... "so much worse."
