Unfortunately, it didn't scale well for large development. I got a similar description from Rational techies at the time. In addition, they explained to me that compilation resulted in a "object" already positioned in the "link" memory space. So linking was a rather simple affair. They also described some special attributed of the commonly used operating system stuff which enable even faster execution of command shells. -- Samuel T.
