TreeBrowser supplies an easy to use graphical environment for collections of formulas and shows them in a tree structure. The equations are passed to the built-in solver of the HP 49G/49G+/50G for solving.
TreeBrowser allows you to create your own collections of formulas easily and quickly. TreeBrowser supports an unlimited depth of the trees and supports units for the equation and pictures. On a HP 49G+/50G the whole screen (131x80 pixels) is used.
System flag 30 controls if the solver of the HP 48SX or the solver of the HP 48GX is used for an equation.
Download program description for TreeBrowser.
This is the complete Equation Library from Hewlett-Packard containing over 300 equations and including all pictures and units which was first available as a plug-in card for the HP 48SX and was later built into the HP 48GX and HP 48G.
The Equation Library is presented as a sample data set for the TreeBrowser. Equation Library requires at least TreeBrowser Version 3.30 or newer.

TreeBrowserBuilder is an extension to the TreeBrowser. With it one can easily create new or modify existing datasets for the TreeBrowser. Created datasets can be saved as a program, a directory or as a library.
The data sets for the TreeBrowser have been created directly on a PC. Please do not modify the example data set with the TreeBrowserBuilder. They contain code which is not supported by the TreeBrowserBuilder and will surely crash your calculator.
GUISLV is a replacement for the built-in graphical user interface for the HP Solve Application and integrates seamlessly into the calculator. The language depends on the installed MLP.
GUISLV behaves like the built-in solver but uses the whole screen of the HP 49G+ / HP 50G and offers substantial advantages over the built-in one.
- Rapid data entry. Multiple arguments are allowed on the command line.
- The fields are shown depending on the current font.
- A title can be given to the solver at start up.
- A list of variables can be given to the solver at start up.
- If the equation contains built-in constants then they will be filtered out.
- The space of the help line can be used as an additional line.
- Variables created by the GUI-Solver can be purged easily and thus allowing
a "clean" exit from the GUI-Solver.
GUIMES is a graphical user interface for the built-in Multiple Equation Solver (MES). The language depends on the installed MLP.
CAVEAT: GUISLV / GUIMES is *not* needed by the Multi Lingual Pack for solving equations. But if you install GUISLV / GUIMES then you *must* update the integrated TreeBrowser of the MLP to version 3.20 or newer !
You have been warned.
CAVEAT: Previously released freeware versions of GUISLV are *not* compatible with TreeBrowser 3.20 ! They will *crash* your machine if used with TreeBrowser 3.20 or newer !
You have been warned.
GUISLV / GUIMES is part of the MLP since 12.04.2011 and therefore included if you order the MLP or you may order GUISLV / GUIMES as a stand-alone library.
If GUISLV / GUIMES is installed it will be used as the default solvers for TreeBrowser (from version 3.20 on).
Here is a video that shows how GUISLV / GUIMES is integrated into the MLP: HP 50G Using GUIMES and the Equation Library

All persons, who help to translate the HP to another language and contribute translated messages, will receive a *free* version of the translation engine including the translated messages so that your HP will talk in your mother-tongue !
A financial program containing programs for annuity repayment, linear computation of pensions, TVM and cash flow.
Linear annuity amortization is the process of dividing a constant payment into the amount that applies to interest and the amount that applies to principal until the debt is paid back completely. Payments near the beginning of a loan contribute more interest and less principal than payments near the end of a loan. Using linear interest for the periods during the year which is the common way used by banks one has to use the relative interest for the periods i* = i/m. Internally this interest is used by the program.
Linear computation of pensions is used for compounded interest calculations that involve regular uniform cash flows called payments. The amount of each payment is the same and occurs at regular intervals. The payment period coincides with the interest compounding period.
Investment computation is used to compare a financial investment with alternate financial investments.
