u To store an X = constant expression * 1
○ ○ ○ ○ ○
Example To store the following expression in memory area X4 :
X = 3
3 (TYPE) 4 (X=c) (Specifies X = constant expression.)
d (Inputs expression.)
w
(Stores expression.)
• Inputting X, Y, T,
r
, or
θ
for the constant in the above procedures causes an error.

u To create a composite function
○ ○ ○ ○ ○
Example To use relations in Y1 and Y2 to create composite functions for Y3
and Y4
Y1= (X + 1), Y2 = X 2 + 3
Assign Y1

• A composite function can consist of up to five functions.
* 1 A function cannot be stored into a memory
area that already contains a function of a
different type from the one you are trying to
store. Select a memory area that contains a
function that is the same type as the one you are
storing, or delete the function in the memory area to
which you are trying to store.
