Ok, I realize I am not being clear, often I say things before I think them through.

When I being up I/S documentation, I can select the Class Reference option.

From Studio I can look up classes that are in the Class Reference Option.

I tried to do the same thing in Atelier, and was unable to find the command to browse through all the Classes I see in the Class Reference Option. That, is what I am trying to do. I hope that is clear.

John, maybe I was asking two separate things.

When I bring up I/S  documentation, there is an option to go to Class Reference.

When I select that option I can see all Classes in the InterSystems database, that is what I am really wanting to do.

I put the comment in about Samples as an after thought, not really thinking it does not apply to the other question.

I just tried to download Eclipse and got an installation error, unable to read repository.

Here is the log.
