Microsoft® Visual Basic® Scripting Edition
Language Reference |
Used at script level to declare public variables and allocate storage space.
Public varname[([subscripts])][, varname[([subscripts])]] . . .
The Public statement syntax has these parts:
Part Description 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:
upper [,upper] . . .
The lower bound of an array is always zero.
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 ("").
