There isn't one.  You can use this little program:

   10 DIM space% 10
   20 PROCassem
   30 FOR Y%=15 TO 0 STEP -1
   40 Y$=STR$Y%:IF LENY$=1 Y$="0"+Y$
   50 PRINT Y$"> ";
   60 PRINT FNrom
   70 NEXT
   80 END
   90 DEF FNrom
  100 IF Y%?&2A1=0 := "(vacant)"
  110 A%=&8009
  120 a$=""
  130 REPEAT
  140 ?&F6=A% MOD 256
  150 ?&F7=A% DIV 256
  160 CALL start
  170 IF ?&70>31 AND ?&70<127 a$=a$+CHR$?&70
  180 A%=A%+1
  190 UNTIL ?&70=0
  200 :=a$
  210 :
  220 DEF PROCassem
  230 P%=space%
  240 [OPT 2
  250 .start
  260 JSR &FFB9
  270 STA &70
  280 RTS
  290 ]
  300 ENDPROC
