George,
Word (and Excel, Powerpoint) come with a large number of constants like the one you used. When you want to use more of them, I recommend to include the type library which comes with those products. DIAdem makes this very easy : Go to the menu in SCRIPT : "Script"=>"type library overview". From the dialog you select the product your are interested in e.g. "Microsoft Word 11.0 Object Library".
Then click the button "Clipboard". This generates a little code snipped. Goto to your script and insert from clipboard (ctrl+v). What you will see is something like this :
' Microsoft Word 11.0 Object Library
' D:\Programme\Microsoft Office\OFFICE11\MSWORD.OLB
Call AutEdTypeLibAdd("00020905-0000-0000-C000-000000000046", "8.3")
If you now add a line like "MsgBox("wdStory : "&wdStory)" you will teh result you expecct.
