Applesoft BASIC

<lang applesoftbasic>10 DEF FN M(N) = ((A / N) - INT (A / N)) * N 20 FOR A = 1 TO 100 30 LET O$ = "" 40 IF FN M(3) = 0 THEN O$ = "FIZZ" 50 IF FN M(5) = 0 THEN O$ = O$ + "BUZZ" 60 IF O$ = "" THEN O$ = STR$ (A) 70 PRINT O$ 80 NEXT A </lang>

If/else ladder approach

<lang qbasic>FOR A = 1 TO 100

  IF A MOD 15 = 0 THEN
     PRINT "FizzBuzz"
  ELSE IF A MOD 3 = 0 THEN
     PRINT "Fizz"
  ELSE IF A MOD 5 = 0 THEN
     PRINT "Buzz"
  ELSE
     PRINT A
  END IF

NEXT A</lang>

Concatenation approach

<lang qbasic>FOR A = 1 TO 100

  OUT$ = ""

  IF A MOD 3 = 0 THEN 
     OUT$ = "Fizz"
  END IF

  IF A MOD 5 = 0 THEN
     OUT$ = OUT$ + "Buzz"
  END IF
  
  IF OUT$ = "" THEN
     OUT$ = STR$(A)
  END IF

  PRINT OUT$

NEXT A</lang> See also: RapidQ

BBC BASIC

<lang bbcbasic> FOR number% = 1 TO 100

       CASE TRUE OF
         WHEN number% MOD 15 = 0: PRINT "FizzBuzz"
         WHEN number% MOD 3 = 0:  PRINT "Fizz"
         WHEN number% MOD 5 = 0:  PRINT "Buzz"

       ENDCASE
     NEXT number%</lang>
