I havn't used Works for years, but if I remember correctly there used to be an option to save file as with an option for an earlier version of Word.
So look for an option to save as a Word doc, failing that save as RTF file or plain txt.
Microsoft provides a converter for Office programs to open and save Works 6.0-9.0
Once you you can open them, you should be able to copy the contents to a new Word file and save it in Word.
Grumpy just saved me looking for the link.
