Introduction

I’m a believer… a Visual Expert believer that is! 
I develop and support a number of PowerBuilder applications, with the assistance of contract developers. Each developer is a world class PB programmer, but the fact that we are not constantly involved in any single application means we need a "refresher" each time we start a maintenance project. 
Recently we had to make some major enhancements to a PB system.  This is the type of task where the carefully planned inheritance structure of the system usually goes to pot. You see some code that is almost what you need, but you duplicate rather than extending it, for fear of fouling up something that is already running well. 
I had used VE for a year and a half already for small jobs, but this seemed like the perfect opportunity for me to really put the tool to the test.
