Command line operations
The command line is where you enter and edit conunands and objects.
The HP 49G provides numerous tools to assist you when working on the
conunand line. Some of these tools have their own key; others can be
selected from the command line editor’s Tool menu.
Activating the command line
The way you activate the command line depends on whether you intend to
create a new object or edit an existing object.
To create a new object, just start typing. The command line is activated as
soon as you start. (While you can create most objects from the conunand
line, many objects are best created using specific applications. For
example, it will usually be easier to create an expression using Equation
Writer, or a matrix using Matrix Writer.)
To edit an existing object on the command line, select the object from
history or from the stack and:
® in algebraic mode, press (ENTER)
® in RPN
mode, press EDIT.
Note that pressing EDIT in algebraic mode activates whatever application
is best suited to editing the type of object you selected, not the command
line editor. For example, if you selected an expression, pressing
EDIT
activates Equation Writer. To edit the object on the command line, you
must press
