I did some work with Ada. I was then working as a US government contractor, and Ada was more or less designed for these huge projects. I found it singularly incompatible with my programming style. I cut my teeth on Basic on the PDP-11 by DEC, and my way was to write the code, try it out and fix what needed fixing. The Ada program refused to even COMPILE unless things were pretty much all right. Ada and I did not get along!! 😉
