The TI-84 Plus uses the variables listed below in various ways. Some variables are
restricted to specific data types.
The variables
A through Z and q are defined as real or complex numbers. You may store
to them. The TI-84 Plus can update
X, Y, R, q, and T during graphing, so you may want to
avoid using these variables to store nongraphing data.
The variables (list names)
L1 through L6 are restricted to lists; you cannot store another
type of data to them.
The variables (matrix names)
[A] through [J] are restricted to matrices; you cannot store
another type of data to them.
The variables
Pic1 through Pic9 and Pic0 are restricted to pictures; you cannot store
another type of data to them.
The variables
GDB1 through GDB9 and GDB0 are restricted to graph databases; you
cannot store another type of data to them.
The variables
Str1 through Str9 and Str0 are restricted to strings; you cannot store
another type of data to them.
