There are a few universities and community colleges that teach RPG and CL but have never run across one the teaches the AS/400 in other terms (admin, db management, etc.) I reside in So Cal and Long Beach Univ has RPG and Cerritos Community College has CL so there may be one in your area. Of course there’s the enpensive trade schools as well.
Wisconsin has quite a few technical colleges that teach the AS400. I worked at the one in Superior, Wi.
Good Luck – keep us posted
