There are numerous possible values for keyword described in the tables that follow. In these tables, you will notice that some keywords are shown in all uppercase characters, while others are shown in combinations of uppercase and lowercase characters. When you issue the DISPLAY command with any of its keywords, you must enter all of the characters that are shown in uppercase. If a keyword is shown in a combination of uppercase and lowercase characters, you need to enter only those characters that are shown in uppercase.
For example, if you want to view the address space ID that generated an event, you could issue the DISPLAY command by entering D A, D AS, D ASI, D ASID, DISP A, DISPLAY AS, and so on.
