This is a simple game i have programmed that simulate a nanorobot DNA repair system environment. This is the code Alwayse in Apple //e Applesoft Basic:

10 HOME
20 SPEED = 150
30 PRINT "Welcome to Nanorobots DNA repair System": PRINT " ":PRINT " "
40 PRINT "What kind of Organ do you want Nanorobots to repair, Brain, Skeleton, Muscles, Heart": INPUT A$  
50 IF A$ = "Brain" THEN PRINT "Starting DNA Repearing XYZYZXXYZXYZXYXYZXYZYXYZYXYZXYXYZYXYZY DNA Reparied Successfully -o-o-":GOTO 10
60 IF A$ = "Skeleton" THEN PRINT"Starting DNA Repearing   VBGVBGVBGVBGVBGGBVGFBGVBGVBGGVBG DNA Reparied Successfully -o-o-":GOTO 10
70 IF A$ = "Muscles" THEN PRINT "Starting DNA Repearing LOILOILOILOILOILOILOIKIOLIJIOOLKIIGLGKIGO DNA Reparied Successfully -o-o-":GOTO 10
80IF A$ = "Heart" THEN PRINT "Starting DNA Repearing WEDWEDWEDWESDWEWEDWERRWEDWEDE DNA Reparied Successfully -o-o-":GOTO 10
90 IF A$ <> "Brain" THEN GOTO 10:IF A$ <> "Skeleton" THEN GOTO 10:IF A$ <> "Muscles" THEN GOTO 10
100 IF A$ <> "Heart" THEN GOTO 10
