Borland was huuuge. The name was so prominent, my college-mate one day (without a hint of irony) said: "All this time I thought the first name of Pascal - the mathematician, was Borland and that's how the company got the name. I just learned I was wrong, it's Blaise..."

When Hejlsberg left Borland to work at Microsoft and then made C# and .NET, etc., I followed like a blind, newborn kitten. And then I spent years drinking that kool-aid. I regret this decision to this day. What a waste of my youth.

So long ago, I don't even recall the name.

They had a C++ GUI library, much better than MFC that came later and eclipsed it.

EDIT: Found it. It was called OWL
