What do I need to do now to ensure that datalog files will not become obsolete with changes in the future?
I'm developing a LabVIEW program to test and record calibration data for manufactured products. In addition to acquiring data, the user inputs a variety of information as part of the record. (i.e. Customer Name, Test Date, Operator Performing the test, etc.) Because changes are a way of life, I know I'll be in trouble if I later change the datalog type. Changes are likely to be the addition of data, but it may also involve deletions. What can I do to ensure that previously saved files will not become unreadable by new revisions in the program? I've considered saving "spare" data fields, but this seems archaic and there are still uncertainties. I'm using LabVIEW v.7.1 with Windows 2000.
