Does USAGE IS DISPLAY stores data item in binary of its ASCII (Hex) values?
Does it takes the value as char irrespective of its PIC, even if PIC IS 9?

The article your link points to is poorly written. If you had read all of it, it tells you what is actually done when you add two display items in COBOL. They are first converted to a computational format (COMP-3 or PACKED DECIMAL for an IBM MAINFRAME) then added and converted back to the proper format for the results.

For a link you should use the URL tags and not the QUOTE tags
