Is it possible to count the number of arguments passed in VB Script function or sub?

you can pass the arguments as an array and get the Ubound of the array. you should get the number of arguments passed to the function or sub.

Hi HanSolo,

No; the parameters to a VBScript Sub or Function are determined
by its declaration - no ParamArray as in VB(A).

You may pass an array/a dictionary to a Sub or Function and treat this as a
kind of do it yourself variable argument list:

   doIt Array( "1", "a" )
   doIt Array()
   doIt Array( "whatever", 2, 3 , 4 )

Sub doIt( aParms )
   ...
   Select UBound( aParms )
       Case -1
            ....
        Case 2
            ....
        Case 3
            ....
        Case Else
            ....
   End Select
...
End Sub

Good luck!
