VBScript has two types of arguments... Named and Anonymous and they are provided as follows:

C:> cscript.exe /nologo script.vbs /CycleDate:01-12-2005 /Test:2 Arg1 
+Arg2 Arg3
[download]

This results in three Collection Objects Arguments(), Arguments.Named() and Arguments.UnNamed()

These will have elements

'VBScript, not Perl
Arguments.Named("CycleDate") 'value="1-12-2005"
Arguments.Named("Test") 'value="2"
[download]

There should be three elements of Arguments.UnNamed() with values "Arg1", "Arg2" and "Arg3".

If you're converting you might use Getopt::Long - then you'd have GetOptions( "CycleDate"=>\$cycledate ...) or warn...
