[thelist] [ASP] Empty arrays in different versions

[Peter Wakeford]

Josh,
here's the official MS VB scripting documentation for it below. The function
should always return false if the expression contains more than one
variable.  In the example it's a variant array (use typename() or vartype()
to determine)


Description
  Returns a Boolean value indicating whether a variable has been
initialized.
Syntax
  IsEmpty(expression)
  The expression argument can be any expression. However, because IsEmpty is
used to determine if individual variables are initialized, the expression
argument is most often a single variable name.


Remarks
  IsEmpty returns True if the variable is uninitialized, or is explicitly
set to Empty; otherwise, it returns False. False is always returned if
expression contains more than one variable.
