Apple had made the HFS+ file system freely available prior to the availability of Mac OS X.
The specifications, and the source code, I believe, are available from the Apple developer site.
IBM System/36 has SSP as its operating system, not S/36, and it's hardly a mainframe--it's a mini computer.
COBOL programmers are certainly out there and aging, but many of them made small fortunes during the Y2K craze, correcting the mistakes they originally coded. RPG/II and RPG/III programmers are in similar situations. Their operations counterparts are much better off.
I would hope that the money of the world would not be trusted to anything else but these two languages (RPG and COBOL) since most programming languages only feature real/floating point numbers which innately have rounding errors. A banking system using C, C++, Objective-C, Java would be worthless outside the classroom as there's always a strong possibility that the numbers are all wrong.
The very stable Zortech compilers became the flaky Symantec C/C++ compilers, both for Macintosh and DOS/Windows.
Symantec bought the Think C and Pascal compilers for the Macintosh earlier. These compilers had approximately 97 percent of the market, and Symantec lost total market share within about 3 years, to Metrowerks.
