Using DB50X with the DM32 is quite difficult without a keyboard overlay.
|
||||
|
||||
In particular, an unfortunate difference between the DM32 and the keyboard
|
||||
layout used by DB50X is that the placement of all letters after `M` is shifted
|
||||
by one position on the keyboard, and the first row of scientific functions
|
||||
(starting with square root and ending with _Σ+_) is inconsistent. The reason is
|
||||
that the layout for DB50X is heavily based on the DM-42 model.
|
||||
|
||||
Also, while the DM32 has two shift keys, a blue and a yellow one, it lacks
|
||||
dedicated cursor movement arrow keys, a limitation that is visible in the
|
||||
calculator's firmware menus. While the two arrow shift keys would be welcome,
|
||||
not having arrow keys for cursor movement is just not an option. As a result,
|
||||
only the blue shift key is kept as a shift key, and the yellow shift key is
|
||||
converted to an arrow key, along with the DM32 _XEQ_ key.

|

Some keys that have little use or no direct equivalent for RPL are remapped
|
||||
as follows:
|
||||
|
||||
* _Σ+_ is used to call [ToolsMenu](#ToolsMenu), which select a menu based on
|
||||
context, notably the content of the stack.
|
||||
Using DB50X with the DM32 is quite difficult without a keyboard overlay.
|
||||
|
||||
* _Σ-_ (i.e.🟨 _Σ+_) will select [LastMenu](#LastMenu), i.e. return to the
|
||||
previous menu.
|
||||
In particular, an unfortunate difference between the DM32 and the keyboard
|
||||
layout used by DB50X is that the placement of all letters after `M` is shifted
|
||||
by one position on the keyboard, and the first row of scientific functions
|
||||
(starting with square root and ending with _Σ+_) is inconsistent. The reason is
|
||||
that the layout for DB50X is heavily based on the DM-42 model.
|
||||
|
||||
* 🟦 _Σ+_ selects [MainMenu](#MainMenu), the top-level menu giving access
|
||||
to all other menus and features in DB50X (see also the [Catalog](#catalog)
|
||||
feature).
|
||||
Also, while the DM32 has two shift keys, a blue and a yellow one, it lacks
|
||||
dedicated cursor movement arrow keys, a limitation that is visible in the
|
||||
calculator's firmware menus. While the two arrow shift keys would be welcome,
|
||||
not having arrow keys for cursor movement is just not an option. As a result,
|
||||
only the blue shift key is kept as a shift key, and the yellow shift key is
|
||||
converted to an arrow key, along with the DM32 _XEQ_ key.
|
||||
|
||||
* _XEQ_ opens an algebraic expression, i.e. it shows `''` on the command-line
|
||||
and switches to equation entry. It can be remembered as *Execute Equation* and
|
||||
can be used to evaluate expressions in [algebraic mode](#algebraic-mode)
|
||||
instead of RPN. While inside an equation, _XEQ_ enters parentheses.
|
||||
|
||||
* _GTO_ opens the [BranchesMenu](#BranchesMenu), with RPL branches and loops,
|
||||
e.g. `IF` `THEN` or `DO` `WHILE`, as well as conditional tests.
|
||||
In the rest of this document, the shift key is referred to as 🟨, and pressing
|
||||
it twice is referred to as 🟦, irrespective of the appearance of the physical
|
||||
shift key on your particular hardware.
|
||||
|
||||
* _COMPLEX_ opens the [ComplexMenu](#ComplexMenu), not just build a complex
|
||||
like on the DM32. The [ComplexMenu](#ComplexMenu) includes features to enter
|
||||
complex numbers in rectangular or polar form, as well as complex-specific
|
||||
functions like [Conjugate](#Conjugate).
|
||||
|
||||
* _RCL_ opens the [VariablesMenu](#VariablesMenu) menu listing user variables.
|
||||
This plays the role of _VAR_ on the HP48.
|
||||
|
||||
* _%_ (🟨 _RCL_) opens the [FractionsMenu](#FractionsMenu), to access operations
|
||||
on fractions.
|
||||
|
||||
* _R↓_ will open the [StackMenu](#StackMenu), containing operations on the
|
||||
stack.
|
||||
|
||||
* _π_ (🟨 _R↓_) will open the [ConstantsMenu](#ConstantsMenu) (π being one of
|
||||
them), with the option to get the symbolic or numerical value. The values of
|
||||
constants come from a file named `CONSTANTS.CSV` on disk.
|
||||
|
||||
* _X⇆Y_ executes the matching [Swap](#swap) function
|
||||
|
||||
* _LAST x_ (🟨 _X⇆Y_) executes [LastArg](#LastArguments) command, recalling the
|
||||
arguments of the last command. There is also a [LastX](#LastX) command for
|
||||
compatibility with RPN, which is available from the [StackMenu](#StackMenu).
|
||||
|
||||
* _Undo_(🟦 _X⇆Y_) restores the previous state of the stack. This is like
|
||||
`Last Stack` on the HP48, but it is a real command that can be used in
|
||||
programs.
|
||||
|
||||
* _+/-_ executes the equivalent RPL `Negate` function
|
||||
|
||||
* _Modes_ (🟨 _+/-_ ) calls the [ModesMenu](#ModesMenu), with submenus for
|
||||
various settings, including computation precision, display modes, etc.
|
||||
|
||||
* _Obj_ (🟦 _+/-_ ) calls the [ObjectMenu](#ObjectMenu), with various
|
||||
object-related operations.
|
||||
|
||||
* _Disp_ (🟨 _EEX_ ) calls the [DisplayModesMenu](#DisplayModesMenu), which
|
||||
controls settings related to the display, such as number of digits shown or
|
||||
separators.
|
||||
|
||||
* _Clear_ calls a [ClearThingsMenu](#ClearThingsMenu) with options to clear
|
||||
various items, including [ClearStack](#ClearStack) and
|
||||
[ClearMenu](#ClearMenu).
|
||||
|
||||
* _SST_ and _BST_ (🟨 _▲_ and _▼_) move the cursor *up* and *down* in the text
|
||||
editor. In direct mode, _BST_ selects the *Best* editor for the object, and
|
||||
*Sst* selects single-step evaluation.
|

* _SOLVER_ (🟨 _7_) shows the [SolverMenu](#SolverMenu), with submenus for
|

numerical and symbolic solvers.

* _∫f(x)_ (🟨 _8_) shows the [SymbolicMenu](#SymbolicMenu), with symbolic and
|
||||
numerical integration and derivation features.

|
||||
matrix delimiters in RPL. 🟦 _9_ shows the [MatrixMenu](#MatrixMenu) with
|
||||
operations on vectors, matrices and tensors.
|
||||
|
||||
* _STAT_ (🟨 _÷_) shows the [StatisticsMenu](#StatisticsMenu)
|
||||
|
||||
* _BASE_ (🟨 _4_) shows the [BasesMenu](#BasesMenu), with operations on
|
||||
based numbers and facilities for entering hexadecimal numbers.

||||
* _CONVERT_ (🟨 _5_) shows a [UnitsMenu](#UnitsMenu) with units and and
|
||||
conversion functions.

|
||||
system flags.

functions such as [Factorial](#factorial), [Combinations](#combinations) or
|
||||
[Random](#random).

||||

* _ASSIGN_ (🟨 _1_) makes it possible to assign any function to any key. These
|
||||
special functions are then selected by using _Custom_ (🟨 _2_), which
|
||||
corresponds roughly to _USR_ on the HP48.
|
||||
|
||||
* _PGM.FCN_ (🟨 _1_) shows the [ProgramMenu](#ProgramMenu), with all
|
||||
general-purpose programming operations, categorized as sub-menus.

||||
* _PRINT_ (🟨 _-_) shows the [IOMenu](#IOMenu).

|
||||
cancels the current activity. It can also be used to interrupt a running
|
||||
program.

||||
|
||||
* _OFF_ (🟨 _EXIT_) shuts down the calculator. The state of the calculator is

||||
preserved.

* _SAVE_ (🟦 _EXIT_) saves the current state of the calculator to disk. This
|
||||
state can be transferred to another machine, and survives system reset or

firmware upgrades.

|
||||
example to load the original DM32 program, activate USB disk, and to access
|
||||
some calculator preferences.
|
||||
|
||||
* _Show_ selects the [ShowMenu](#ShowMenu), with various ways to display objects
|
||||
on the stack, such as [ShowBest](#ShowBest), [ShowSymbolic](#ShowSymbolic),
|
||||
[ShowGraphical](#ShowGraphical), [ShowCompact](#ShowCompact).
|
||||
|
||||
* The _R/S_ keys inserts a space in the editor, and maps to
|
||||
[Evaluate](#evaluate) otherwise.
|
||||
|
||||
* _PRGM_ (🟨 _R/S_) inserts the delimiters for an RPL program, `«` and `»`,
|
||||
while 🟦 _R/S_ inserts the list delimiters, `{` and `}`.
|
||||
|
||||
* _CATALOG_ (🟨 _+_) shows a complete context-sensitive catalog of all
|
||||
available functions, and enables auto-completion using the soft-menu
|
||||
keys. Note that the `+` key activates the catalog while in *Alpha* mode.
|
||||
|
||||
* _HELP_ (🟦 _+_) activates the context-sensitive help system.
