VBScript Public Statement

Used at script level to declare public variables and allocate storage space.

Syntax: VBScript Public Statement

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

Arguments: VBScript Public Statement

varname

The name of the variable; follows standard variable naming conventions.

subscripts

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

upper [,upper] . . .

The lower bound of an array is always zero.

Remarks: VBScript Public Statement

Variables declared using the Public statement are available to all procedures in all scripts in all projects.

A variable that refers to an object must be assigned an existing object using the Set statement before it can be used. Until it is assigned an object, the declared object variable has the special value Nothing.

You can also use the Public 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 Private, Public, or Dim statement, an error occurs.

When variables are initialized, a numeric variable is initialized to 0 and a string is initialized to a zero-length string ("").

The following example illustrates the use of the Public statement:

Public MyNumber ' Public Variant variable.

Public MyArray(9) ' Public array variable.

' Multiple Public declarations of Variant variables.

Public MyNumber, MyVar, YourNumber
