uFunction 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.

•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.
