I am using IBM Clear Case and from Studio we use UserAction=3 to run some executable commands to launch cleartools functions for "Check-Out", "Check-In", etc.

Now I am exploring the idea of use Atelier, but still tied to IBM Clear Case. By reading your comments it looks like I may have to go for the option to create a template/page to handle these actions or maybe wait for a possible migration to RTC Source control and the hope of some plug-in available to hook up with Atelier.

Thanks for your quick answer.
