I agree, I can't possibly convey how much I learned from some old IBM fiche that I had access to in the computer center when I just started college. The first really important thing I wrote (I was 17) were mods to pass the condition codes from step to step within JES2 and then send the highest one to the console and syslog at job end. I later learned that others had done the same thing, and long before me, but I learned a lot. That code didn't work with the first version of MVS I was exposed to after college, so it was followed by doing that same thing with two jes exits and then even later writing our companies Automation software that pulls the condition codes from the same fields they were placed in originally way back then.
Everything I have written over the years is still based on concepts and techniques that I first learned by looking at the code in the IBM fiche. I had an extra advantage in that I worked for IBM throughout that same time and was able to see some truly spectacular coding techniques and I am truly thankful for that opportunity. I realize that IBM wanted to keep nefarious people from copying the code, but I think that we lost a great deal of experience and expertise when we lost access to the code. Some of those techniques are just not around for people to examine and learn from, and that's very sad.
