Hello Julia,
The cch() Function belongs to the calculator which, of course, can be called inside the ANALYSIS module. But if you are looking for a specific dialog in one of the ANALYSIS menus, I am afraid I have to dissapoint you. If you want to calculate the mean value interactively, you can use the option inside the statistic dialog - which calls a different function to get the result though.
Alternatively, you can always create a custom dialog with the SUD tool.
I am not sure if I got qour qestion 100% right, so if that does not answer it, just reply.
