of GSOS or clipart off the net.

10 hgr
20 print chr$(4);"bload screen,a$2000"
30 x=1:y=1:rem selection
40 hcolor = 0
50 gosub 500:rem erase selection
60 if peek(-16384)>127 then get a$
70 if a$="j" then x=x-1
80 if a$="l" then x=x+1
90 if a$="i" then y=y-1
100 if a$="k" then y=y+1
110 if x<1 then x=1
120 if x>14 then x=14
130 if y<1 then y=1
140 if y>9 then y=9
 200 hcolor = 7
 210 gosub 500

500 hplot (x-1)*20,(y-1)*20 to ((x-1)*20)+20, (y-1)*20 to
((x-1)*20)+20, ((y-1)*20)+20 to  (x-1)*20, ((y-1)*20)+20 to (x-1)*20,
(y-1)*20
