(...) Sure, but that's what zero padding is for. Since the opcode is IR-only, you don't care too much about length. The only length restriction comes from the second digit of the opcode, assuming you're using the ROM to receive incoming IR data. (...) (25 years ago, 10-May-99, to lugnet.robotics.rcx)
