The TI.83 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.83 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.83 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,
n
Min, and
other window variables.
• ZXmin, ZXmax, ZXscl, ZTstep, ZPlotStart, Zu(
n
Min), and
other ZOOM variables.
The variables below are reserved for use by the TI.83. You
cannot store to them.
n, v, Sx, sx, minX, maxX, Gy, Gy2, Gxy, a, b, c, RegEQ, x1, x2,
y1, z, t, F, c2, Ç, v1, Sx1, n1, lower, upper, r2, R2 and other
statistical variables.
