I was wondering about the point system of stock markets

I've been reading about the Wall Street Crash in 1929, and noted that after the crash, it was not until about 20 years later for the market to pass 200 points. Currently the Dow is at 18,570, I was just wondering if there was a way to measure the difference in these two points? Given the difference in purchasing power, inflation, etc.

Thanks
