Allows you to conveniently switch back to the application in use when you switched to or launched CalcWorks. The name of that application is shown in place of 窶---窶. This is also the application that will be switched to when CalcWorks is iconized or minimized if those options are enabled in Preferences.
Minimize
Reduces the full or 4-function calculator windows to a display-only window. See 窶廬conizing and Minimizing窶.
Iconize
Reduces the full or 4-function calculator windows, or the minimized display window, to an icon on the desktop. See 窶廬conizing and Minimizing窶.
Show / Hide Tape Window
Shows the tape window if it is currently hidden, or hides it if it's showing. If Automatic tape logging is turned on in Preferences, then calculations will not be logged to tape when the tape window is hidden.
Turn Logging On / Off
Turns logging on if it is currently off, or off if it is currently on. When tape logging is turned on, all calculations are logged to the tape window. This command is disabled if Automatic tape logging is turned on in Preferences, as in this case tape logging is automatically enabled when the tape window is shown, and disabled when is is hidden. In any case, the state of this command always reflects the current logging state.
Set Number Format...
Displays the Number Format dialog, allowing you to set the number display format. See 窶廸umber Format Dialog窶.
Key & Color Setup...
Displays the Key & Color Setup dialog, allowing you to assign keys to calculator functions. See 窶廳ey & Color Setup窶.
Sequential, Algebraic, RPN
These three commands allow you to set the operating logic used by CalcWorks. Sequential evaluates all operations in the order entered (ie. 1+2*3 is evaluated as (1+2)*3, and the result is 9). Algebraic ordering evaluates operations in the order dictated by standard algebraic rules, delaying operations as necessary (ie. 1+2*3 is evaluated as 1+(2*3), and the result in this case is 7). RPN, or Reverse Polish Notation, is a special operating logic used in some HP calculators, in which the operands are entered first, separated by [Enter], and the operator is entered after the operands (ie. 1+2*3 would be entered as 2 [Enter] 3 [ x ] 1 [ + ]).
When switching to RPN mode, several buttons change to support the standard features of RPN-based calculators. The [ = ] button changes to [Enter], and shifted-[Enter] changes to [Last], the LAST X feature of RPN. The parenthesis open and close buttons change to the stack roll up and down buttons, which shift the stack up or down one register at a time. The [CE/C] button changes to [CLX] (clear X), and [AC] changes to [CLS] (clear stack). See 窶彜equential, Algebraic, and RPN窶 for more information on these modes.
Automatic Constant
Checking this command enables CalcWorks' automatic constant, unchecking it disables it. See 窶廣utomatic Constant窶 for more information on the effect of the automatic constant on calculations.
Keypad Emulation
Checking this command automatically maps the keyboard keys M, J, K, L, U, I, and O to the calculator numeric buttons 0, 1, 2, 3, 4, 5, and 6 respectively. The use of these keys in conjunction with the 7, 8, and 9 keys directly above them, simulates a numeric keypad on those systems that do not have one (such as PowerBooks).
Startup Iconized
Checking this command will force CalcWorks to always start up in the iconized state, and bring the launching program (usually the Finder) to the front. You would usually only select this option if you place an alias of CalcWorks in the Startup Items folder in the System folder to automatically launch the calculator at system startup.
