The paper tape window automatically records all calculations performed in either the main calculator, reduced calculator, or minimized display. All operating mode and number formatting changes are also recorded internally. Using the tape window, you can easily verify your important calculations on-screen or after printing. CalcWorks includes the option to print your calculations to a neatly formatted columnar printout, with the tape document name, time and date at the top of each page. The printout can be formatted to any page size or orientation by selecting the desired options in the Page Setup dialog. You can save your tape calculations to a tape document at any time. Also, because CalcWorks saves all calculator state information with each tape entry, you can later reopen a saved tape document, and continue with your calculations right where you left off! All operations and memory registers will be restored as long as you stored them with tape logging turned on. This works by running each number and operation on the tape back through the calculator, as if you had just entered them in by hand (numbers are stored on the tape in their internal format, which retains their original precision).
There are several options that control and/or effect the tape window. The Automatic tape logging option (in Preferences) and tape logging switch (in the Options menu) control whether CalcWorks saves calculations to tape. If Automatic tape logging is enabled, calculations are saved only when the tape window is showing. If Automatic tape logging is not enabled, you can manually enable or disable tape logging by selecting the Turn Logging On / Off command in the Options menu. The Log intermediate results option (in Preferences) determines whether results of intermediate operations are logged to the tape (when you press the 窶+窶 button, for instance, an intermediate result is displayed in the calculator's main display). The Prompt to save changes option (also in Preferences) determines whether CalcWorks warns you before erasing the contents of the tape window. The Thousands separator option (in the Number Format dialog) determines whether thousands separators are shown in the tape window. Finally, of course, the Show / Hide Tape Window command (in the Options menu) shows or hides the tape window. There is also an option in Preferences to automatically save the tape window contents each time CalcWorks is quit. This option is enabled only if CalcWorks is registered.
All numbers logged to the tape are displayed in the number format in effect at the time it was logged, with the exception that numbers are always expressed with 10 digits in the mantissa. Numbers logged with Lock Units in effect are logged in decimal format. Numbers logged in binary [Bin] mode are truncated to the low word or lower 16 bits (in display only, the entire number is retained in calculations). Changes in number format do not effect previous numbers on the tape.
Tape documents can be opened from the Finder by double-clicking the document or selecting the document and choosing Open from the Finder's File menu. Only a single document can be opened at a time (if you try to open multiple documents, only one will be opened). You can also print directly from the Finder by selecting the document or documents and choosing Print from the Finder's File menu. All selected documents will be printed by CalcWorks. CalcWorks can either be running or not when documents are opened or printed from the Finder. While a document opened from the Finder replaces the current tape document in the tape window if CalcWorks is running, printed documents do not effect the tape window in any way.
