Variables declaration is the same as variable creation because the computer is instructed to reserve the memory space. The variable can be named according to your preference. There may be short names such as a, b or c, or more authentic ones such as client, address, amount, etc. It is considered good programming practice to render clear and descriptive names of variables.

Rules for Declaring Variables −

• The Variable Name should start with an alphabet.
• The Variable names cannot surpass 255 characters.
• The Variables must not include a period (.)
• The Variable Names should be different in the stated context.

Using the "Dim" keyword, the variables are specified. Since just ONE basic data type is available, all variables specified are variants by default. Therefore, while declaring, a user does not declare the type of data.

Assigning Values to the Variables

Similar to an algebraic expression, values are assigned. On the left side of the variable name is followed by a symbol (=), and on the right side is the variable's value.

Rules for assigning the variables

• The numeric values must be stated without double-quotes.
• Date and Time variables must be confined within the hash symbol(#)
• The String values must be confined within double quotes(")
