Well, 0x60 for you PC folks. If I remember correctly, hex 60 (96 decimal) was the code for RTS on the 6502/6510 microprocessor. So you could have just ended the list a bit short of 100 ($64) and it still would have been a "round" number (nothing in the one's place, at least, in hex).
Doing it in hex, stop at $60
