If you think of the array as a matrix, the first argument represents the rows and the second argument represents the columns. For example, the following statement declares a 2-dimensional, 5-by-10 array. In Visual Basic, you can declare arrays with up to 60 dimensions. MsgBox "Data for " & varData(0) & " has been recorded." For example, the following statement can be added to either of the preceding examples. You identify the elements in an array of Variant values by index, no matter which technique you use to create the array. VarData = Array("Ron Bendel", "4242 Maple Blvd", 38, _ The other way is to assign the array returned by the Array function to a Variant variable, as shown in the following example. One way is to declare an array of Variant data type, as shown in the following example: Dim varData(3) As Variant There are two ways to create arrays of Variant values. You can also explicitly set the lower bound of an array by using a To clause, as shown in the following example. In the following example, the Option Base statement changes the index for the first element, and the Dim statement declares the array variable with 365 elements.

Use the Option Base statement at the top of a module to change the default index of the first element from 0 to 1. The following example assigns an initial value of 20 to each element in the array. To set the value of an individual element, you specify the element's index. By default, an array is indexed beginning with zero, so the upper bound of the array is 364 rather than 365. The following statement declares the array variable with 365 elements. Each element in an array contains one value. Refer to the array as a whole when you want to refer to all the values it holds, or you can refer to its individual elements.įor example, to store daily expenses for each day of the year, you can declare one array variable with 365 elements, rather than declaring 365 variables. An array is a single variable with many compartments to store values, while a typical variable has only one storage compartment in which it can store only one value. You can declare an array to work with a set of values of the same data type.
