my code now is....

DIM TC AS INTEGER, TANK AS STRING
TANK$ = "U5 R5 E5 F5 R5 D5 L20"
TC = 33
SCREEN 12: CLS : DRAW "C14" + TANK$
DO
LOCATE 1, 1
ARROW$ = INKEY$
SELECT CASE ARROW$
CASE CHR$(0) + CHR$(75): IF TC > 1 THEN DRAW "C0" + TANK$ + "C14 BM -10,0" + TANK$: TC = TC - 1
CASE CHR$(0) + CHR$(77): IF TC < 62 THEN DRAW "C0" + TANK$ + "C14 BM +10,0" + TANK$: TC = TC + 1
CASE CHR$(0) + CHR$(72):
CASE CHR$(27): SYSTEM
END SELECT
LOOP
