Holy Crap - I haven't heard the term JCL since I worked at IBM when I was a high school student. Living in IBM country, they took a few of us on as late afternoon interns hoping to recruit us after college. Last gasp of the old-style mainframe lifestyle. I got to work with that newfangled first portable computer, the 5100 I think? Everything was coded in APL on those...Stupid floating point. We'd build analytic models in SAS and the 8.3 floating point wouldn't translate correctly from the SAS code to the JCL on the IBM system..... it's the same file....
Years ago when I built computers we had a bug in the floating point math hardware of the CPU.
Not a huge discrepancy but for some reason they rounded differently and the models required perfection and the proofs would constantly fail. It was the bane of my existence for almost a year.
And referring to floating point bugs - was that the infamous Pentium FDIV fail? I was working as a consultant at Intel back then but I swear was never near that part of the design ;-)
Wow, ghosts from the past. Like the old saying goes, "Someday we'll look back at this, laugh nervously, and try to change the subject..."
