I see "never been any consideration" as a failure of the designers to step back and ask themselves, "What will be the customers' perception of this behavior?" <snippage> The customers in those days actually read the doc and could, in many cases, program the thing from the display station as well as wire the plug boards for the external units. So, the customers came to see that DISP= was a DATA SET LEVEL disposition. At least this customer had that understanding. And when I wrote this for a Univac system, their equivalent of disposition was for the file not the data within the file.
