I guess Steve means that if you create symbols of code bits that you use in several places, then you update one of them, and the others will be updated automatically.

Yea Byron,

If your not using them you are missing out on a huge benifit to SD4! Here is a link to an article explaining how to use them in your navigation https://www.coffeecup.com/help/articles/syncing-with-symbols/

If you have any questions please let us know.

Thanks guys - will look into this

Byron
