Learned quite a bit. Well presented. Though, without access to a mainframe to practice and experiment, this stuff learned will fade away. Would be nice to see a COBOL/Db2 course from IBM

Even though I'm a Civil Engineer I always want to learn how IBM programs their mainframes. Might as well program one someday

The courses are too short and simple.
