Note that you can import additional commands from third-party
conunand libraries. When a library is attached, the commands in the
library will appear in the conunand catalog. If any such conunand begins
with a character that is not available directly from the HP 49G keyboard,
you will not be able to search for the command.
Typing commands
In addition to selecting a command from tire conunand catalog or from a
menu, you can also enter a conunand by typing its name on the conunand
line.
For example, to factorize an expression while in algebraic mode, you
could:
1. type igP0(IPHA)FACTOR00
2. enter the expression
3. press (ENTER).
To factorize an expression while in RPN mode, you could:
1. enter the expression onto level 1 of the stack
2. type (SMldPHA) FACTOR
3. press (ENTER).
Every command found in the command catalog can be entered directly
from the keyboard.
Some conunand names contain special characters (for example, ^ and
Z). The Characters catalog—accessed by pressing
0¡CHARS) and explained
in chapter 2 of the User’s Guide—shows the keystrokes needed to enter
special characters.
