Hello everyone! I want to create a large queue of jobs, but I don't know how to do it. Currently, when I submit a job to the card reader, it completes instantly in 0 seconds. This is frustrating

Andre, It is not the case that there was "no such thing" as a UPS (uninterruptible power supply) or deisel generators in the 1970s.? It was only the very largest of installations with multiple CPUs

I agree with you. I am privileged because I have not only lots of books and

During the night shift most of the development and testing was done. Card decks were submitted up until office closing time. No development decks were run whilst the reservation system was going

On the contrary. ?IBM made excellent manuals, the best of the industry. ?They do require some knowledge as the foundation. ?How did most of us get that knowledge? ?It was by trial and error and

Vince That simply isn’t true for a modern PC. The i5 chips have multiple memory buses, and PCI Express provides IO which is also inherently multi-channel. My run of the mill laptop, with a

Your micro may well have multi drives - my desktop/server has around 6 including a SSD BUT they all transfer data from and to the same data bus and that is sued for all other transfers such as

Harold, Assembler is intriguing to me. I started by using Sinclair ZX Spectrum back in 80s, and remember reading a book about assembler, but never tried it back then. Principles of Operation book is

Hi Fran, Has anyone checked the professor's program? What if it contains mistakes? I believe that mainframe time was quite expensive. Best wishes, Andre

Hello Vince, I always thought that even Pentium CPU was much faster than 370 m/fs. Well, i agree, m/f has a lot of disks, but you can attach 4 or more HDDs to your PC also. For example, i have two

Based on your question#s : Evening and night shift (of 8 hours) was because the early mainframes and that included as far as I was involved in IBM 1401, 360 and early 370s, ICL 1900's (1500 as well

Andre asked: “Why did night shifts exist?” The basic answer is that compared to today’s computers the IBM 360 and 370 computers were quite slow. You just could not get all of the work done

As a travel company, we ran a reservations system by day ( CICS c 100 x 3270 terminals ). Overnight batch accounting, reports, backups overnight and development and testing streams. CICS programs

Hi Steve! This is so cool! Do you have any more stories about working on 370? What type of programs usually was batched through the day? Business stuff? Scientific? I know that ENIAC was used to

As an operator I learnt assembler on a 370/138 on dos/vs after reading Sharon K Tuggle’s Assembler Language Programming book. On night shifts I would squeeze in a few programs in BG. To drive it

The Principles of Operation manual is an absolute must for assembly language programming. ?You simply can not program in assembler without it. At the moment you are struggling with how to get the

Dear Mike, I have to say, i am a big fan of moshix and Rene Ferland. So i am pretty familiar with 370VM 6pack and DOS/VS installation under it. But i appreciate your advice. Sincerely, Andre

I would also suggest that you download and run the VMr6 package from http://www.vm370.org/VM/V1R1.2 The VM forum is here : /g/h390-vm Vm, is the easiest IBM os to get up and running

Tommy Sprinkle's site is all in assembler code As for the "rc" scripts, nothing is stopping you from opening them in your favorite editor to look /change whatever. You will see that most of the rc

Hello Mike! Thank you for replying. Tommy Sprinkles site looks very interesting, but maybe i should end up learning assembly language first. Also, you know what? I already finished DOS360 sysgen by
