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.
