Cimplicity - list of tags used in screens only

Hi All, we're analysing a legacy Cimplicity project and are looking to extract a list of tags. However we only want a list of tags that are used in the display screens, is this possible?

We thought the Point Xref Explorer might be the place but this appears to display only those in Data Tables, Group Tables, scripts etc, not screens.

We're in the process of writing a script to scan the CTX files, wanted to check if there was something available in the front end.

cheers,
Pete

This is what I would do:
1. Backup the project.
2. Export all tags to a csv file.
3. Delete unused tags.
4. Export to a csv file with a different name.
5. Analyze the difference in Excel.
Assuming that most or all of the unused tags are "valid" they are the ones used 'only' by the HMI.
Of course this may be slightly flawed, but it will minimize the manual analysis.
