Memory usage

The amounts of memory the calculator uses for variables, programs and equations are shown below.

Variables

Each variable uses 1 byte, and each local variable uses 9 bytes to store its value.

Programs

Creating a new program uses 32 bytes of memory irrespective of the length of its name.

Each line in a program uses 3 bytes plus the number of characters or commands on the line (each character or command uses 1 byte). For example, the two lines of the program shown below use 60 bytes.
