In one of my interview he asked me like "what happen if you try to open a file in EDIT mode if that file contain some 100 thousands of records" he want me to open the file through ISPF screen with Option 3.4. I simply given answer like "I never opened that much big file" My question is Do we get any error or he just tried to create some confusion.
I don't know if you tried this but usually it should be Browse substituted.
I think as I remeber we can edit files of this volume in File Manager/File Aid
Frankly speaking I did not try this one. I was failed to find out that much big file as I am not dealing with that much big files. One more reason to ask this query is just I would like to know "Is there any limit and if I can not open in EDIT mode there must be some reason behind that".
