Literal Subscript Operator

Keystroke: . [period]

v_init

This subscript is strictly for naming purposes. To use it:

1. Type the first part of the name (v), the part that comes before the subscript.

2. Type a period followed by the subscript name (init).

Notes:

• Be sure not to confuse literal subscripts with array subscripts. Although they appear identical, they are quite different. Literal subscripts represent a name for your variable. Array subscripts imply the creation of a vector or matrix of the size specified by the subscript. When you click on a literal subscript, the period is revealed to help you distinguish it from an array subscript.
• For example, typing v.20 := 10 results in a scalar variable named v₂₀ whose value is 10. However, typing v[20 := 10 results in a vector v of 21 elements, the last element of which is 10, and the previous 20 elements of which are 0 (assuming ORIGIN of 0).
• You can change the display of the subscript using the Display tab under Worksheet Options.
