Dim Statement

Declares variables and allocates storage space.

                      Dim varname[([subscripts])][, varname[([subscripts])]] . . .

Arguments

• varname
  Name of the variable; follows standard variable naming conventions.

• subscripts
  Dimensions of an array variable; up to 60 multiple dimensions may be declared. The subscripts argument uses the following syntax:

  upperbound [**,**upperbound] . . .

  The lower bound of an array is always zero.

Remarks

Variables declared with Dim at the script level are available to all procedures within the script. At the procedure level, variables are available only within the procedure.

You can also use the Dim statement with empty parentheses to declare a dynamic array. After declaring a dynamic array, use the ReDim statement within a procedure to define the number of dimensions and elements in the array. If you try to redeclare a dimension for an array variable whose size was explicitly specified in a Dim statement, an error occurs.

For more information about using the Dim statement to create variables and arrays, see Visual Basic Scripting Edition (VBScript) Variables.

The following examples illustrate the use of the Dim statement:

                      Dim Names(9)       ' Declare an array with 10 elements.
Dim Names()        ' Declare a dynamic array.
Dim MyVar, MyNum   ' Declare two variables.
