Do a file open, append line of data, file close with each reading. THis is a trivial activity for the computer. Then to satisfy the customer, have the save button copy the contents of this "Shift" file to a final file. That way, if there is a power failure (and the operator has not hit the save button for 4 hours) and the customer calls you, you can tell them to look for this "shift file" to get the data they thought long gone. DUring a machine startup and or shut down, you can have the contents of the file saved to the daily file then purge the "shift" file.
