My first job out of university was working with a very large firm that bought into Computer Associates' product suite - including 4GL code generators such as Telon ("green-screen" generators) and Easytrieve (4GL report generators). From what I recall, we spent 90% of our time trying to work around the code generators to accomplish tasks, as opposed to simply using native CICS, which was difficult to master (hence the 4GL). I've since used a number of 4GL-type tools, and they've all had the same limitation in that the tail wags the dog, to use an old idiom. Quite fast and seemingly magical if you stay within the guardrails, but as soon as you veer off course (and unless you don't want any differentiators, you will) they quickly become far more onerous than hand-coding, plus lock you into their 'forced march': cost, upgrades, incompatibilities, and so on. As an aside, it was a very interesting time to be a developer as we had a mix of youngsters (me), who were raised on personal computers, many people seasoned on mainframes/mid-range computers, plus a few "old-timers" who started coding in the 1950s without any formal training. Everyone had great stories, and I feel lucky to have been exposed to people firsthand who were some of the first programmers (and they universally thought everything above assembly language was 'cheating'). Their stories and perspectives have stayed with me throughout my career.
