Have you ever wished to do two calculations at the same time with your conventional adding machine? I suppose that has happened more than once, maybe all the time.
You can use auxiliary tapes to organize, and work simultaneously with, several separate but related calculations.
With DeskCalc these days are gone. You can create up to 10 tapes at the same time. An auxiliary tape has all of the same capabilities as the main tape. Press the TAB key to switch from one to the other, or SHIFT+TAB for to opposite direction.
You may give your tapes different names, save them to file and reload them at any time.
DeskCalc does print your tapes and add these tapes names as a note, as well as the user that created the calculation + time and date. All of this is optionally.
