I found a webpage in the DOS beginner section called "Learning Information." Following the method taught there (the section on DOS features), I tried entering "TIME" and "DATE" to check the time and date, and entering "DIR" to view the drive directory. But what was displayed here was somewhat different from what was taught on the webpage. Then when I entered "MEM" to check memory usage, it seemed like nothing came out at all, completely different from the illustration on the webpage. What's going on?
