BSGS sequential save progress

[yusefgharib]

Hi, how would you save progress on a BSGS sequential search? Or start where you left off? Say you searched for 1000 keys and your range was 2000:fffff or something. Would you find a hex calculator and add 1000 to the starting range or convert the 1000 to hex and add it? Or is there an easier way to do this
