Home variables

It is not possible to store data of one type in a variable of another type. For example, you use the Matrix catalog to create matrices. You can create up to ten matrices, and you can store these in variables M0 to M9. You cannot store matrices in variables other than M0 to M9.

Category	Available names
Complex	Z0 to Z9
	For example, (1,2) 672?aZ0 or 2+3i 672?a￿
	Z1. You can enter a complex number by
	typing (r,i), where r represents the real part,
	and i represents the imaginary part.
Graphic	G0 to G9
	See “Graphic commands” on page 15-20 for
	more information on storing graphic objects
	via programming commands. See “To store
	into a graphics variable” on page 14-5 for
	more information on storing graphic object
	via the sketch view.
Library	Aplet library variables can store aplets that
	you have created, either by saving a copy of
	a standard aplet, or downloading an aplet
	from another source.
List	L0 to L9
	For example, {1,2,3} 672?aL1.
Matrix	M0 to M9 can store matrices or vectors.
	For example, [[1,2],[3,4]] 672?aM0.
Modes	Modes variables store the modes settings that
	you can configure using >6+,)7@MODES.
Notepad	Notepad variables store notes.
Program	Program variables store programs.
Real	A to Z and θ.
	For example, 7.45 672?aA.
