Editing Equations
1. Make sure the Solve catalog containing the equation you wish to edit is
displayed.
2. Highlight the desired equation. If you highlight the name, you will be able to
edit the name. If you highlight the equation itself, you can modify it, as well.
3. Press [F2) (A=FRD.
4. Make the changes that you want. The arrow keys work just as in Memo Editor.
When you've finished, press (ENTER).

Equation ( .EQN) Files
Each equation you enter goes into a particular Solve Catalog; each Solve Catalog
is stored as an EQN file. An EEN file is a text file (which you can edit in the
Memo Editor or other text editor—in addition to the editing offered with the Solve
feature). Like any other file, an «EBM file can be transferred between a PC and
the HP 95LX using the Filer and Connectivity Pack (see page 93)—so you can type
in equation on a desktop PC and then transfer it to the Palmtop to use!
Suppose a particular «EBM file contains three separate equations (Hamel,
Namez2, and Name3). The file would look like this when viewed in Memo Editor
or other text editor:
{Name | Equation text of the first program 3
{Mame2 | Equation text of the second equation >
{Name3 | Equation text of the third program
Each individual program is contain within brackets, <2, and the name of each
equation is separated from its equation by the vertical bar, |. Neither of these
delimiters is visible when you view a single equation within the Calculator Solver.
A single «EBM file can contain up to about 38 kB—a lot of equations! You can
therefore feel quite free to include in each « EGMfile all equations you might want
access to during one Solver session.
