In VBSCRIPT, unlike standard VB, variables don't have a type. Basically, they are all of type "variant".

Dim bInfo as Boolean ' works with VB, breaks in VBSCRIPT
Dim bInfo ' declares a Variant, works with VB & VBSCRIPT

Writing 'Dim x as ...' will always break in VBSCRIPT.
Note that you don't _have to_ explicitly declare variables. Doing so permits faster execution, though.

Also, there is the question of scope, as illustrated by your 'Global bInfo as ...'. In the latest version of VBSCRIPT, the scope of any variable (declared or not) is the ASP Page, unless it is declared in a function or sub, in which case the scope is limited to the function.

Dim x ' page-scope
x = 2

Sub foo ()
      Dim y ' lives inside of foo()
      y = 2 * x ' y equals 4
      .... ' do sth with y
End Sub

Sub bar()
      Dim x ' x is a local var
      x = 3 ' won't affect x which was declared at the page level
End Sub

Call bar
if x = 2 then ' condition is true
.
end if

Henceforth, there are no global variables in VBSCRIPT. You may however store variables at the session level, using :
 
Session("bInfo") = True ' available for all pages within the session

or at the application level :

Application("bInfo") = True ' available for all pages, all sessions/users, until the server is shut down.
