Use the VECTOR Mode to perform 2-dimensional and 3-dimensional vector
calculations. To perform a vector calculation. you first assign data to special
vector variables (VctA. VctB. VctC). and then use the variables in the
calculation as shown in the example below.
h To assign (1. 2) to VctA and (3. 4) to VctB. and then perform the
following calculation: (1. 2) + (3. 4)
1.Press @!!)III (VECTOR) to enter the VECTOR Mode.
2. Press (I)(VctA)!I)(2).

Whenever the result of a calculation executed in the VECTOR Mode is a
vector. the VctAns screen will appear w~hthe result. The result also will be
assigned to a variable named "VctAns".
The VctAns variable can be used in calculations as described below.
" To insert the VctAns variable into a calculation. perform the following key
operation: I!!iIIII(VECTOR) III (VctAns).

Assigning and Editing Vector Variable Data
Important: The following operations are not supported by the Vector Editor:
1iID.I!!ilIiID(M-). I!!iI ~(STO). Pol. Rec. +R. and multi-statements also
cannot be input with the Vector Editor.
To assign new data to a vector variable:
1.Press I!!iIIII (VECTOR)(I) (Dim). and then. on the menu that appears,
select the vector variable to which you want to assign data.
2.On the next menu that appears. select dimension (m).
3. Use the Vector Editor that appears to input the elements of the vector.

select the vector variable you want to edit.
2. Use the Vector Ed~orthat appears to ed~the elements of the vector.

To copy vector variable (or VctAns) contents:
1.Use the Vector Ed~or to display the vector you want to copy.
" If you wantto copyVetA,forexample,performthe followingkeyoperation:

2. Press I!!ilIi!!!I(STO). and then perform one ofthe following key operations
to specify the copy destination: 8(VctA). B(VctB). or ffij(VctC).
"This will display the Vector Editor with the contents of the copy
