The information in this article applies to:

 - Microsoft Visual Basic Learning, Professional, and Enterprise Editions
   for Windows, version 6.0
 - Microsoft Visual Basic Control Creation, Learning, and Professional
   Editions for Windows, version 5.0
 - Microsoft Visual Basic Standard, Professional, and Enterprise Editions,
   16-bit and 32-bit, for Windows, version 4.0

SUMMARY
=======

This article shows you the type declaration characters and corresponding
data types. A Type Declaration Character is a character appended to a
variable name indicating the variable's data type. For example, the
variable name MyString$ has a dollar sign appended to the variable name and
is dimensioned as a String data type.

MORE INFORMATION
================

The following table shows the type declaration characters and corresponding
data types.

Type Declaration Character  Data Type
--------------------------  ---------
          %                 Integer
          &                 Long
          !                 Single
          #                 Double
          $                 String
          @                 Currency

Even when using type declaration characters, you still need to declare your
variables when you have Option Explicit at the beginning of the Module.
Using Option Explicit is recommended to prevent problems due to misspelled
variable names. When "Require Variable Declaration" is checked in the
Editor Tab of the Options dialog box from the Tools Menu, Option Explicit
is added to new Modules automatically. If you use Option Explicit, but you
do not declare your variables, you will receive the following error message
at run-time:

   Compile Error
   Variable Not Defined

To prevent this error from occurring, you can either remove Option Explicit
or explicitly declare your variables. Using type declaration characters
allows you to shorten these statements. For example, you can use this:

   Dim MyVar$

instead of this:

   Dim MyVar As String

Both statements declare MyVar to be a memory variable of type String.
