I was replying to an AC that referred to the language as COBAL, hence the intended misspelling.
I worked for a large financial corporation starting with peripheral operations on punch card readers, and microfiche printers long ago. I've worked with removable platter DASD, on DEC PDP-11/70's through Tandem Himalaya machines, then into Unix and Solaris on SUN and Cray hardware. It sounds like we have similar backgrounds. I did mention that there was huge price to just get into the game at the mainframe level though. I've had to debug more hex dumps in old JES environments than I care to remember
