I wasn't sure whether to post here under networking or in the os section. I am starting to take some computer classes at the local community college. I am looking to get into networking. I am currently taking an AS/400 class. Someone told me that AS/400 is becoming obsolete. I was also going to take Programming in RPG and COBOL, which are programming languages used in AS/400. I don't want to waste my time if this is true. I can't understand why. One thing I learned is that AS/400 is one of the most reliable network operating systems around. This was only one person who told me this so I don't know if he knows what he's talking about. Does anybody know if this is true, if AS/400 is becoming obsolete? And would I be wasting my time if I took RPG and COBOL?
