Re: [EpiData-list] Re: EpiData-list Digest, Vol 78, Issue 6

Say market ID is 3 and shop ID is 25.

Then the code for the market/shop combination is 3 * 100 + 25 (3 times 100 plus 25) = 325

Of course, this only works if the IDs are numbers.

But pls do you know the function of the " *100+ " between market ID and shop ID?
