Pop-ups and menu bar

Using pop-up menus

The Simulator provides several pop-up menus. Pop-up menus are invoked by clicking with the right mouse button on a user interface element, e.g. a button, the display etc., or by a keyboard shortcut of the form Altkey.

If you invoke a pop-up menu by clicking a user interface element, its top left corner appears near the mouse pointer. If you invoke the pop-up with a keyboard shortcut, the top left corner of the pop-up appears at the bottom left corner of the GUI element.

In addition to the pop menus, a menu bar can be switched on.

Mac OS X specifics

Mac OS X does not allow coloured items or fixed width fonts in pop-up menus. Both features are needed for the simulator pop-up menus. Therefore pop-up menus are derived from normal windows; i.e. other than those under Windows or Linux they have title bar. These pop-up menus can be used with a mouse only. The arrow keys can not be used to move the cursor.

Under Mac OS X the menu bar is always on as it serves as the application's standard menu bar.

ON Menu

The ON pop-up menu provides functions that are typical for a "File" menu.
Menu item Shortcut Description
Open program… CtrlO Open a HP-15C program file. Opens the operating system standard "Load file" dialogue box to select a file. The new program will override the current program(s) when loaded.
Save program… CtrlS Save the current HP-15C program(s) to a file. Opens the operating system standard "Save file" dialogue box to specify a file.
Program description… F12 Opens the Program Description dialogue box. Used to edit/enter program documentation.
HTML help: text CtrlF1
Displays the HTML file for the current program.
If a HTML file is available, "text" is the file name without an extension. If no file is found, the "text" is "<not available>" and the menu entry is greyed out.
Clear storage registers ShiftEsc Set all storage registers to zero.
Memory ▸ - Memory submenu. See below.
Stay on top CtrlT HP-15C stays on top of other applications on the desktop even if it hasn't the focus.
Swap comma and period Alt.
This swaps the representation of the decimal point and the digit separator.
Preferences… Ctrl,
This entry opens a dialogue box that allows you to configure the Simulator. See Preferences for details on configurable items.
Help F1 Displays the Simulator online help while in Run mode or the help file for the current program (if available) in PRGM mode.
Show back side - Shows the back side of the HP-15C simulator.
About HP-15C… - Opens a dialogue box showing the Simulators copyright, disclaimer, serial number and other information.
Exit AltF4 Shuts off the Simulator.

Memory submenu

Menu item Shortcut Description
Save memory CtrlM Save the Simulator memory to disk. Path and file name depend on the operating system and can not be changed by the user.
Load memory CtrlL Reload the Simulator memory.
Reset memory CtrlR Reset the memory to the default value.

Stack Menu

This menu shows the status of the stack. That is, the values of the numbers stored in each of the four stack registers and in the last x register.

The stack menu is available only in Run mode, not in PRGM mode.

Selecting one of the menu entries X through T performs a stack roll down. The selected register becomes the X register. Selecting the entry LSTx performs a push on the stack and copies the contents of the LSTx register to the X register.

Numbers in the pop-up menu are formatted in the same way as in the display. Let us assume you have keyed in the following:

1 2 ex g √x̅ (or )


7 7 7 7 7 7 ⅟x

4 2

f 7 2 (or simply FIX 2)

When you right click the display, you will see the pop-up menu as shown in the first column:

stack_fix2.gif 189x114 stack_fix4.gif 189x114 stack_sci3.gif 189x114

The key sequence f 7 4 gives the format shown in the second column and f 8 3 that in the third column.

In Complex mode, the stack pop-up menu displays both the real and the imaginary stack:

Storage Menus

This menu displays the status of the storage registers.

Depending on whether you invoke the menu on the STO key or the RCL key, the menu is either in storage or in recall mode. Selecting a register in recall mode will copy the contents of that register to the X register. In storage mode the contents of the X register is copied to the selected register.

By default, the storage menu is displayed in two-column mode. It can be changed to one-column mode in the Preferences dialogue box.

two-column mode one-column mode
storage_2cols.gif 386x226 storage_1cols.gif 193x426

As with the real HP-15C, the user can change the number of available registers with f DIM (i). The pop-up menu will show only the registers currently defined, but a maximum of 20 registers, plus the I register. If, for example, the user has limited the number of registers to 7, the pop-up menu will look like this:

one-column mode two-column mode

Program Menu

This menu shows the current program steps in a multi-column list. It is the equivalent of the real HP-15C function GTO CHS # # # (where # is in [09]) which moves the program pointer to the step with the given number.

In PRGM mode the menu is invoked by:

In Run mode the menu can only be invoked by:

If you select a program step from the menu, the program pointer is positioned on that step. In PRGM mode, the selected program step will also show up in the display.

Three settings affect the layout of the menu (see Preferences).

The following figure shows some examples of pop-up menus:

CodeCode and colourMnemonicsMnemonics and colour
prgm_code.gif 142x206 prgm_code_col.gif 142x206 prgm_mnemonics.gif 142x206 prgm_mnemonics_col.gif 142x206

By default, the menu displays coloured mnemonics.

◀ PRGM Menu ▲ Top

Flag Menus

This menu shows the status of the 10 flags.

A value of "1" indicates that a flag is set ("on"), a values of "0" that it is not ("off"). The flags 1 through 7 are user-defined flags. Flag 8 indicates whether or not the Simulator is in Complex mode. Flag 9 indicates the blinking of the display.

When you select a menu entry in PRGM mode, the key sequence "43. 6. N" to inquire the status of Flag "N" is inserted in the program. Selecting a menu entry in Run mode has no effect.

Test Menu

The test menu provides access to the 10 compare operations not directly accessible from the keypad.

The test menu is available only in PRGM mode, not in Run mode.

The HP-15C has 12 different compare operations. Two of them, x≤y and, x=0, are accessible directly from the keypad. The ten remaining through g TEST n, where n indicates the code of the operation:

test_menu.gif 106x206

When you select a menu entry in PRGM mode, the key sequence "43.30. N" to perform test "N" is inserted in the program.

Error Menu

If an error occurs, the HP-15C displays the word "ERROR" followed by the error code. The error pop-up menu provides a decoding for the error numbers.

98File I/O Error Error while opening or saving a program file
99Tcl/Tk Error Tcl/Tk interpreter error

This is, of course, no error code of the real HP-15C. Although the Simulator has been tested a lot, there may be some undetected errors in the code.

When you come across such an error, it may happen that even restarting the Simulator does not solve the problem. In this case, the HP-15C memory file must be deleted manually.

Pr ErrorMemory error Continuous memory was reset

The memory of the Simulator was reset to the default values.
