The thing that struck me from coming from a unix background was that the entire OS was record aware, all the native tools, everything. Stuff that is just hard in unix is trivial in z/OS

- Taniwha 7y agoHaving grown up in the older 'record aware' systems unix bytestreams were a wonderful breath of fresh air (this was back in v6/v7) - I guess perspective is everything
- rbanffy 7y agoBeing record aware comes from the punched cards that were the most popular way to keep data when they started evolving. They were born before ASCII (they use EBCDIC and, while ASCII was supported in one early IBM 360 model, it was dropped almost immediately) Unix was born after magnetic storage, both disk and tape, were common. A file looks a lot like a tape.
- Aloha 7y agoSystem/360 was supposed to be ASCII from the get go, the architecture supports it (the RCA Spectra 70 series which was a System/360 architecture system was ASCII). All System/360 descendants support ASCII, the issue they ran into early in the System/360 program was accessories, IBM had lots of EBCDIC I/O devices, and developing a line of ASCII I/O devices would have delayed introduction of the line by a period of time.
- rbanffy 7y agoThe USASCII-8 mode bit in the program status word existed in all 360's (sorry about that) but was removed in the 370.
- Aloha 7y agoIdeally I want both things.
