But note that z/OS is also an Open Group certified Unix through its Unix System Services (opengroup.org/openbrand/register), which also include methods for on-the-fly translation between EBCDIC and ASCII/UTF-8. | |

| Jul 9, 2020 at 9:23 | comment | added | Michael Kay | And you ask a fourth question "[Did] IBM [make] ASCII [a] world wide standard?" To which the answer is a simple "no". IBM might have used ASCII very early on in some of their products, but IBM adopted ASCII because it was already a standard in use by nearly everyone else. The main point here is that ASCII's origins are in the telecomms industry, not in computing. | |

| Jul 9, 2020 at 9:06 | comment | added | Michael Kay | The question in your title "When did IBM start to use ASCII?" is completely different from the two questions in your first paragraph "When did IBM switch to using ASCII?", and "When did ASCII [become a] worldwide standard?". The three questions have quite different answers, and in all three cases the answer depends a lot on how you read the question. | |

| Jul 9, 2020 at 1:52 | comment | added | dave | @RosieF - sure, I agree ASCII is a 7-bit code. I do not agree that if you assign meaning to codes > 127 then it is somehow still using or supporting ASCII. And anyway, CP 437 (for example - the original IBM DOS codepage) is not even congruent with ASCII in codepoints 0 to 31. | |

make it clearer

| Jul 8, 2020 at 21:36 | comment | added | smci | "When did IBM start to use ASCII?" (in any model of computer? teletypes?) and "When did IBM mandate using ASCII across all hardware, computers and teletypes?" are different questions. The answer to the former is apparently ~1964 (the 2260 terminal) but the answer to the latter is probably "sometimes between 1968-early 1970s". | |

| Jul 8, 2020 at 19:50 | comment | added | Rosie F | @another-dave That's all the codepoints ASCII has. If an OS supports a superset of ASCII, a fortiori it supports ASCII. | |
| Jul 8, 2020 at 17:49 | comment | added | dave | operating systems running on the IBM PC and its descendants use ASCII It doesn't seem that way to me when you look at the plethora of DOS code pages. They may be similar to ASCII in the first 128 or so codepoints, but that does not make them ASCII. | |
| Jul 8, 2020 at 15:25 | comment | added | RichF | Perhaps it is incorrect to say ASCII become a word wide standard. Better to refer to ISO-8859 (sometimes referred to as "ANSI") as the standard. The first 128 characters are the same as ASCII, but the last 128 incorporate many other elements of Western European alphabets such as accented vowels, ñ, ß, etc. Then, as ANSI extended ASCII to Western Europe, Unicode extended ANSI to the world. | |

| Jul 8, 2020 at 7:46 | comment | added | JeremyP | AIX is a variant of Unix. I wouldn't be at all surprised if their proper operating systems (most 370's et al do not run AIX natively) still use EBCDIC, or, if not, they'll have moved to some variant of Unicode. | |
