Ok.
But the problem is, if I enter something like 'm' or 'y' (it's outside de
type Mytype is (a,b,c)), the data_error exception is raised one time by the
get, then tests is recursively called. So  I have to enter again something.

But if I enter something like '*','%','/' instead of a letter like 'm', the
Data_Error is raised and tests is recursively called again and again until
storage_error and stack overflow. It doesn't stop!!!

Thks!
