A friend recently asked me what training it takes to work with the IBM AS/400. I gave a brief answer mentioning some college courses, some on-the-job training and a long time in the school of hard knocks. But upon reflection, I realize that most of my training in the fundamental concepts of the AS/400 came

What is a load all subfile? A load all subfile is one in which we generally specify the subfile size as 9999 in the record format itself. However, you may define the subfile size to be less than 9999 in the record format and still load all your subfile at a time. In that situation
