When writing code in the VBA Editor, users need variables that they can use in the code to hold a value. By declaring a variable, the user is essentially telling the computer to reserve memory space for later use, allowing the VBA code to run smoothly. If the data type is not specified when declaring the variable or the variable is not declared at all, the variable will default to the variable data type that can accommodate any data type. When declaring variables to hold an integer using the Dim statement, use the code “Dim rowNumber as Integer.” The term “Dim” should appear at the preceding part of a variable. Variables should be declared using Dim, Private, Public, or Static statements. The data type can either be an integer, text, decimal, Boolean, etc., whereas the variable level can be either procedure level, module-level, or public scoop. By declaring a variable, the user provides information to the VBA compiler about the variable data type and other information such as the level.
