There is a 10-level numeric value stack, a 26-level command stack, and a 10-level program subroutine stack. An error occurs if you perform a calculation so complex that it exceeds the capacity of available numeric value stack or command stack space, or if execution of a program subroutine exceeds the capacity of the subroutine stack. Example Numeric

Some of the functions that require one byte are: b, c, d, sin, cos, tan, log, In, , and π. Some of the functions that take up two bytes are d/dx(, Mat, Xmin, If, For, Return, DrawGraph, SortA(, PxIOn, Sum, and an+1. When the number of bytes remaining drops to five or below, the cursor automati- cally changes from “ _ ” to “ ”. If you still need to input more, you should d

1-2 Memory kkkkk Variables This calculator comes with 28 variables as standard. You can use variables to store values to be used inside of calculations. Variables are identified by single- letter names, which are made up of the 26 letters of the alphabet, plus r and θ. The maximum size of values that you can assign to variables is 15 digits for the mantissa and 2 digits for the exponent. Variable contents are retained even when you turn power off. uuuuuTo assign a value to a variable [value] a [
