The TI-82 STATS 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-82 STATS 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.
You can store any string of characters, functions, instructions, or
variables to the functions
Yn, (1 through 9, and 0), XnT/YnT (1
through 6), rn (1 through 6), u(n), v(n), and w(n) directly or
through the
Y= editor. The validity of the string is determined
when the function is evaluated.
The variables below must be real numbers. You may store to
them. Since the TI-82 STATS can update some of them, as the
result of a
ZOOM, for example, you may want to avoid using
these variables to store nongraphing data.
• Xmin, Xmax, Xscl, @X, XFact, Tstep, PlotStart, nMin, and
other window variables.
•
ZXmin, ZXmax, ZXscl, ZTstep, ZPlotStart, Zu(nMin), and
other ZOOM variables.
The variables below are reserved for use by the TI-82 STATS.
