VBA Variables

Variable is a specific memory used to hold values that are stored in a storage system and computer memory. You can use these values in the code, and it can be changed during script execution. The computer fetches these values from the system and shown in the output.

Each variable must be given a name. Some are the basic rules to name the VBA variable, such as:

  • You must use the letter as the first character or not begin with a number.
    For example, you can't write a variable name which starts from a number as "1_hello", the correct way is "hello1".
  • Name must be less than 255 characters.
  • No space, period (.), exclamation mark (!), or characters (@, #, $, *) is allowed.
    For example, you can't write "Student ID" as it contains the space between Student and ID, the correct way of representing this variable name is "StudentID".
  • You can't use "Visual Basic" reserved keywords as a variable name.
  • The period is not allowed.

Syntax for VBA variable

you need to declare the variables before using them by assigning names and data type, in VBA.

In VBA, variables are either declared implicitly or explicitly.

Implicitly: let's see through an example of a variable declared implicitly.

  • Label = javaTpoint
  • Volume = 10

Explicitly: let's see through an example of a variable declared explicitly.

  • Dim Num as Integer
  • Dim password as String

VBA variable is not different than other programming languages. To declare a variable in VBA, you can use the "Dim" keyword in syntax.

How to Execute the Variables

Before we execute the variables, we need to record a macro in Excel. To record a macro, follow the steps which are given below:
