Reading PI Annotations and then Writing PI Annotations For Digital and Integer Tags

I have been trying to get a bit of code working for a while and it works half way right now.  What I need to do is first check a tag value to see if it has an annotation and then if it does not I perform another test and if it passes the test I want to annotate the value to indicate it was used.  Right now I can read if the annotation exists but I think I need to get the correct traps in place to write an annotation.  Does anyone have some code snippets for this kind of operation?  I also think there is an issue when updating a digital tag with an annotation once I have packaged the annotation and want to write it to the tag value.

 

Any help is appreciated.
