Years in IT—
My first mainframe job—
After college, I helped improve an written-in-house assembler job scheduling package for Great Western Savings & Loan Association, even though at the time I was working in the nascent PC group. This experience reinforced and reaffirmed my love of IBM System/360 and successor architectures assembler and is why it has been my preferred language, no matter the operating system (z/OS, z/VSE, z/VM, Linux on z and the non-IBM System/390 architecture BS2000/OSD). If you can't do it in assembler, it can't be done.
My favorite mainframe attribute—
How can I pick just one? However, to me, the most important attribute is that with all the improvements to the original System/360 architecture over the past 50 years, you can still reassemble or recompile a basic program created in the days of System/360 and it will run on z/OS 2.1 (and newer).
