Code points '20'x-'7f'x were not the only important ones. And ASCII was *not* who was "colonizing the 256-character wilderness"; that was PC software, and lots of PC users were bitten by the incompatibilities. To say nothing of users of graphics below '20'x who got bitten by software that treated some of those code points as ASCII control characters rather than the characters from code page foo.

ASCII antedated EBCDIC. EBCDIC was the disastrous outcome of IBM's struggle to meet schedule and cost targets when IBM "bet the future of the company" on the S/360. IBM won; customers lost. ASCII suffered a "jungle of incompatible code pages" similar to that of EBCDIC -- consider the ISO-Latin variants. But ASCII had a practical path to UNICODE because ASCII, unlike EBCDIC, kept important code points static. EBCDIC made the irreparable mistake of overloading common code points rather than colonizing the 256-character wilderness as ASCII did. And IBM missed a more recent opportunity by not making z/OS UNIX System Services ASCII-based like the original IBM PC. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
