When You Finish Entering Data into an Input Form
Input forms are designed to help you enter data and prepare to
execute a larger task. The data you enter and options you select may
either be used only within the context of the particular input form and
its tasks, or they may cause global changes throughout all applications.
Changes to reserved variables (such as EQ) and system flags are
examples of global changes.
Whether or not these global changes are saved depends on how you
exit the input form. The following procedures illustrate your options:
To execute the main action of an input form:
1. Make sure the necessary data is entered and proper options
checked.
2. Press the appropriate action key (particular to each form).
Global changes are saved and the action executed, displaying the
appropriate screen. This does not usually cause you to exit the
input form.
To exit the input form after saving any global changes:
■ Press OK from the menu. Sometimes it is shown only on the
second page (press (NXT ), if necessary.)
To exit the input form and discard any global changes"
■ Press
( cancel )
or CFiHCI...... Sometimes CFiNCL is shown only on the
second page (press (NXT~), if necessary.)
To exit SOLVE input form and open PLOT input form (and vice-
versa):
■ Open the new input form. Global changes are saved and all
non-global data is discarded before the current input form is exited
and the new input form opened.
Input Form Commands
The HP 48 has several programmable commands you can use to create
your own customized input forms. These commmands, located in the
PRG IN command menu, are discussed briefly in appendix G, and in
detail in the
HP 48G Senes Advanced User’s Reference.
