    Dim a As String      'Declares the variable "a" as a String'
    Dim a$, b As Integer 'Declares one variable as a String and one as an Integer'
    Dim c As Boolean     'Declares c as a Boolean variable that can be TRUE or FALSE'

Once you have declared a variable as a certain type, you cannot declare the variable under the same name again as a different type!

When you declare multiple variables in a single line of code you need to specify the type of each variable. If the type of a variable is not explicitly specified, then Basic will assume that the variable is of the Variant type.


  ' Both variables "a" and "b" are of the Integer type
  Dim a As Integer, b As Integer
  ' Variable "c" is a Variant and "d" is an Integer
  Dim c, d As Integer
  ' A variable can also be explicitly declared as a Variant
  Dim e As Variant, f As Double

The Variant type is a special data type that can store any kind of value. To learn more, refer to the section The Variant type below.

Option Explicit

The Option Explicit statement has to be the first line in the module, before the first SUB. Generally, only arrays need to be declared explicitly. All other variables are declared according to the type-declaration character, or - if omitted - as the default type Single.

Integer variables range from -32768 to 32767. If you assign a floating-point value to an integer variable, the decimal places are rounded to the next integer. Integer variables are rapidly calculated in procedures and are suitable for counter variables in loops. An integer variable only requires two bytes of memory. "%" is the type-declaration character.

Single variables can take positive or negative values ranging from 3.402823 x 10E38 to 1.401298 x 10E-45. Single variables are floating-point variables, in which the decimal precision decreases as the non-decimal part of the number increases. Single variables are suitable for mathematical calculations of average precision. Calculations require more time than for Integer variables, but are faster than calculations with Double variables. A Single variable requires 4 bytes of memory. The type-declaration character is "!".

Double variables can take positive or negative values ranging from 1.79769313486232 x 10E308 to 4.94065645841247 x 10E-324. Double variables are floating-point variables, in which the decimal precision decreases as the non-decimal part of the number increases. Double variables are suitable for precise calculations. Calculations require more time than for Single variables. A Double variable requires 8 bytes of memory. The type-declaration character is "#".

Currency variables are internally stored as 64-bit numbers (8 Bytes) and displayed as a fixed-decimal number with 15 non-decimal and 4 decimal places. The values range from -922337203685477.5808 to +922337203685477.5807. Currency variables are used to calculate currency values with a high precision. The type-declaration character is "@".

Literals for integers

Numbers can be encoded using octal and hexadecimal forms.


  xi = &o13 '    8 + 3
  ci = &h65 ' 6*16 + 5
  MAX_Integer =  &o77777 '  32767 = &h7FFF
  MIN_Integer = &o100000 ' -32768 = &h8000
  MAX_Long = &h7fffffff '  2147483647 = &o17777777777
  MIN_Long = &h80000000 ' -2147483648 = &o20000000000

String variables can hold character strings with up to 2,147,483,648 characters. Each character is stored as the corresponding Unicode value. String variables are suitable for word processing within programs and for temporary storage of any non-printable character up to a maximum length of 2 Gbytes. The memory required for storing string variables depends on the number of characters in the variable. The type-declaration character is "$".

In BASIC String functions, the first character of the string has index 1.

Dim Variable As Date

Literals for Dates

Date literals allow to specify unambiguous date variables that are independent from the current language. Literals are enclosed between hash signs #. Possible formats are:

#yyyy-mm-dd#
#mm/dd/yyyy#


  start_date = #12/30/1899# ' = 1
  dob = #2010-09-28#

The Variant type

Variables declared as Variant can handle any data type. This means that the actual data type is defined during runtime as a value is assigned to the variable.

There are three main ways to create a Variant variable, as shown below:


  Dim varA            ' The type is not specified, hence the variable is a Variant
  Dim varB as Variant ' The variable is explicitly declared as a Variant
  varC = "abc"        ' Previously undeclared variables are treated as Variants

The example below uses the TypeName function to show how the type of a Variant variable changes upon assignment.


  Dim myVar As Variant
  MsgBox TypeName(myVar) ' Empty
  myVar = "Hello!"
  MsgBox TypeName(myVar) ' String
  myVar = 10
  MsgBox TypeName(myVar) ' Integer

A Variant variable is initialized with the Empty special data type. You can use the IsEmpty function to test if a variable is an Empty Variant.

You can also use the keyword Any to declare a variable as a Variant. However, Any is deprecated and is available for backward compatibility.

Arguments with type Variant or Any passed in function calls are not checked for their types.


  Dim myVar As Any ' Variable "myVar" is a Variant
