Moderator's Interview : Robert Sample

zMainframes: Why do you help on Forums? And what is the message you'd like to give to the new Forum users - rationally, irrespective of their experience in the field?

ANSWER

I like giving back to the community and helping on the various forums I participate in does that. The message I'd give to new Forum users is to learn how to debug -- how to find the messages in the manual, interpret what the messages tell you, and learn to apply that to the specific situation. Also, learn to rely upon the site support group; they can really ease the troubleshooting process.

Moderator's Interview : Robert Sample

zMainframes: Do you use an avatar name here or you use your real name as avatar name? If you are using an avatar name, is there a story behind choosing that name which you might like to share with us?

ANSWER

I use my real name. At a previous employer, a co-worker searched for help on a mainframe question and found one of my online answers. He had trouble believing that it was really me!

zMainframes: How long you have been associated with computers, in general? And since when you've been working with mainframes? Would you like to share your IT experience with us?

ANSWER

I started working with computers in high school in 1971 on a GE time-shared system using BASIC. We connected with an acoustic modem (you dialed the number, waited for the data beeps to start, then put the telephone handset into the modem to connect) and we were thrilled when our line speed was tripled from 110 baud to 300 baud (11 to 30 characters per second). I started with mainframes in college in 1975, working for the computer center as an operator / programmer on a 360/30 using OS/MFT; we had 3 partitions of 32K, 16K, and 16K to run programs in. My first full-time job in 1977 was specifically as a mainframe programmer.

zMainframes: Have you worked on IBM mainframes mostly or you have worked with other vendors too? If yes, could you please name them and do you see a difference among hardware per se?

ANSWER

I've mostly worked on mainframes (IBM and Amdahl both), but I have used DEC PDP 7, HP 3000, HP 2000, and Motorola Four Phase minicomputers at various times. I've always managed to adjust as I see a computer as a computer as a computer.

zMainframes: What difference do you see, from S360 days to zOS 2.x days - ease of use, better interface, more power to end user or something more? Describe it in your own words.

ANSWER

I think the biggest difference is the wide range of uses for the mainframe. It is used with Java, web sites, and many other area not even thought of when it was developed.

zMainframes: In an age of social-media, cloud, DevOps and you name it technology where do you see mainframe in the computer industry?

ANSWER

I think the mainframe continues to be a key technology and don't see that changing anytime in the next 10 to 12 years. The large companies that use mainframes don't see any replacement technology on the horizon.

zMainframes: Why do you help on Forums? And what is the message you'd like to give to the new Forum users - rationally, irrespective of their experience in the field?

zMainframes: What is your take on statements like "millennial are not attracted towards mainframe?" Are we not advertising this platform good enough or there is more to it, your thoughts please.

ANSWER

I think millenials are too young to have a sense of history and hence do not understand the importance of the mainframe. Colleges react to their interests in designing their curricula, so mainframes are not often taught despite their importance to the industry. Executives in those companies with mainframes are very much aware of the lack of new people and are taking steps to address the issue.
