PaulS,
I would like one file, one reading and the date and time stamp to correlate DO to brix in a fermenting barrel of wine. The user defined number will be the 5 digit barrel number. We're looking to see with a few hits of oxygen from a stone at different intervals affects the rate of fermentation and temperature. I'm looking for an easy way to differentiate the different times we hit each barrel with O2. Since I can't use more than 8 characters for the file name, I'm thinking of adding a letter to the end of the number sequence to denote the time sequence. This however, runs into the problem that I would need to write out the letter to keep track of which is next in the sequence. If I'm doing that, I might as well write down the time and date as well on a paper list & rename the files to the format I originally suggested once on the computer. That is just more work, and I think there could be a more elegant solution that isn't causing me to spend a bunch of time cross referencing that paper list.
