Clipper was the first programming language I used in anger in a real job, I really enjoyed working with it. At the same company I also designed and implemented an upgrade from IBM PCLP network and DOS desktops to Win 3.1 with a Novell network. Sounds like our paths were fairly similar at the start Steve!
While I do mostly SQL Server now, that foundation of doing everything IT related from ops to development (including underfloor cabling and soldering connectors to wires!) in a small team was a great foundation for what I do today. I would recommend anyone to do as many different things early in their career if they can, a great way to get an idea of what other departments do and you mnight just find something you really enjoy that you hadn't thought of before.
