Anders Hejlsberg wrote the first mass-market Compiler+IDE with Turbo Pascal. What was unique is that TP would automatically bring up the editor and position the cursor on the offending error. Seems trivial now, but it was a game changer for writing code on a PC. TP sold for around $49. The competitor, Pascal MT+, sold for $400.<p>I doubt if Anders would remember me, but I was lucky enough to be contracted by Borland to write their first test suite for TP 4.5. It was their first object oriented language. The spec was one of the most beautiful and concise pieces of technical documentation I&#x27;ve ever read.
