u Function Memory [OPTN] - [FUNCMEM]
Function memory is convenient for temporary storage of often-used expressions. For longer
term storage, we recommend that you use the Graph mode for expressions and the Program
mode for programs.
• { STORE } / { RECALL } / { fn } / { SEE } ... {function store}/{function recall}/{function area
specification as a variable name inside an expression}/{function list}

• If the function memory number to which you store a function already contains a function, the
previous function is replaced with the new one.
• You can also use a to store a function in function
memory in a program. In this case, you must enclose the
function inside of double quotation marks.
