Input Forms
Many of the HP 49G’s applications have input forms to help you remember
the infonnation you need to enter aird to set various options.
An input fonn is just like a dialog box on a
computer. The example on the right—
displayed when you press 0 (TO3)—is the
input form you use to set up a plot.

You need to highlight a field—by moving the
cursor to it—before you can enter or change data in it. You move the
cursor to a field by pressing the arrow keys.
Input Form fields
Each input form has a set of fields, a short help message relating to the
cun'ently highlighted field, and a menu that displays choices relevant to
the cuiTently highlighted field.
Four types of fields can appear on an input form: data fields, extended
data fields, list fields, and check fields.
Data fields
Data fields accept data of a particular kind directly from the keyboard.
The Indep, H-Tick, and V-Tick fields in the above example are data fields.
(These fields—and others on this input fomi—are explained in chapter 4,
“Plotting graphs”.)
To enter or change the data in a data field:
1. Press an arrow key imtil the field is highlighted.
2. Press
EDIT.
Any data in the field is copied to the command line.
3. Enter or edit the data on the command line. (See “Using the command
line” on page 2-7 for infomration.)
Wliere the data is also the name of a variable, your entry will be
evaluated and replaced with the variable’s object. To use the name of a
variable rather than the associated object, enclose the name in single
quotes (that is, tick marks).
4. Press (ENTER) to copy the new data to the input fonn.
