File, Export
Export the fields you want, including "Start Number" and any fields you want/need. You can bring it into excel or anything you can open a delimited (comma or tab) text file.
OR
From the "Competitor" tab, choose "Reports" and "First Run" and "Start List".
Answer the questions as you want such as "Include Club Quota". You might also be asked if you want to sort first (this will depend on whether you have auto sort on or not).
When you see the preview screen, choose "Save to file" and then save this file to a location you can find it, such as your desktop. Make sure you end the file name with a .txt. For example, you should call the file StartList.txt
You can open this saved file in Word, Word Pad, Note Pad or Exel using "Fixed Width" and just delete the headers.
Good luck,
