There are several ways to add subscripts to a new variable.
1 Place the cursor in the variable name box and select a range or subscript.
2 Press the Subscript button to open the subscript text box. Place the cursor in the subscript text box and either type or click on a range or subscript name.
Multiple subscripts
If there need to be two or more dimensions for a variable, simply add the first dimension and then position the cursor appropriately in the subscript text box.
