Sure David, I’ve never been a Systems Programmer other than the last 19 years. Before that, I was a DB2 DBA, DASD Admin, contractor, programmer analyst, manager of operations, programmer, and Operations for one of the largest auto companies on the planet. I’ve worked in numerous industries, large and small companies, and have a Math & Computer Science degree. Not the idiotic 2 year tech degree that many colleges created to fast track kids into a burgeoning IT industry. But keep trying to downplay me idiot.

You said: "... In fact, making changes to delivered software can be dangerous. ..." Writing/modifying Exits is not the same as your statement. It is evident from what you've written, that you've never been a Systems Programmer, the highest mainframe technical calling. Yes, I am being elitist. People who can't/won't code Assembler should know their place and should not be so arrogant in groups like this. It almost seems like you're jealous of those of us who do this for a living. It took 3 of you to modify an IEFUSI?! Hah! How freaking "bush league". Grow up and learn some Assembler.
