It was IBM's answer to the SHARE ASCII/EBCDIC Character Set [ÆCS] Task Force report "ASCII and EBCDIC Character Set and Code Issues in Systems Application Architecture". Sometimes considered to be IBM's riposte to the NIH (that's Not Invented Here - not the [US] National Institutes of Health) "Codepage 37 version 2" proposed in that paper. > Why does it seem to be controversial?

Those CPs, and quite a few more, such as 285, 273, etc. encode what IBM calls Character Set (CS) 697. This CS (or Character Repertoire in ISO terminology) is often called Latin-1, though Latin-1 is also used to mean the ASCII-based encoding of CS 697, which is IBM's CP 819. > What need impelled it? It's worth getting a copy of the SHARE ÆCS report to see what the state of character encoding and standardization was like in 1989.
