Let me stick my neck out and speculate, that what you really want is to use the result at a later time or date. NoteTab can do that too!
You don't even have to bother with file handling.
Take the result from Sheri's calculation, and create PERMANENT variables instead:

Or, you could save the data in 1 step (omitting the temporary variable):
even if you close NoteTab, and shut off your PC, you can retrieve this data the next time you start up again (unless you OVERWRITE the data before that), with:
Read the section about variables in NoteTab help.
