I am an old-school mainframe programmer, specializing in machines that use IBM z/Architecture and predecessors. This includes, but is not limited to, the following operating systems:
- z/OS, including UNIX System Services
- z/VSE
- z/VM
- Linux
- BS2000/OSD
- z/TPF
My speciality is assembler and C programming, but I am an expert in most other languages and tools found on these platforms, including COBOL, PL/I, Rexx, TSO CLIST, Fortran, ISPF…
I live in Roseville, California, USA.
