I have been programming since the early 70s on a wide-variety of operating systems. Here are the languages that I've written major pieces of software for, on the associated environments:

• Univac 1100 Assembler, APL, Basic, Cobol, Lisp, PLUS and Snobol on Univac 1100 Series mainframes.
• PDP-11 Assembler on DEC PDP-11 minicomputers
• Forth on MC6800
• Basic and Fortran on Prime PRIMOS minicomputers (The Prime midicomputer OS, called PRIMOS, was written primarily in Fortran, as well as their major applications, including the Basic interpreter. For a contract, I wrote a major upgrade to the PRIMOS Basic interpreter that allowed very large Basic programs to chain to each other).
• MC68000 Assembler and C on MC68K single-board computers (SBC) (I developed a complete, stand-alone embedded computing environment with a Unix-style memory manager.)
• PLUS on Univac 1100 Series mainframes (PLUS is Programming Language for Systems, a Univac proprietary high-level language.)
• C, PL/1, and DCL on DEC VAX VMS minicomputers. (I developed a print symbiont for a Xerox printer attached to a DEC VAX VMS system.)
• C, Unix Shell, Emacs Lisp, Awk, Make, n/t/roff, SQL, Perl on IBM AIX, HP HP-UX, DEC Ultrix, and SGI Irix workstations (10 years of managing network and computer systems and staff at a UC campus.)
• Python, Ruby, Awk, HTML, Java, Javascript, Make, SQL, Unix Shell on Apple Mac OS X servers and laptops. (Financial data management using proprietary algorithms)
