Sorry for the unclear post. Around 1983, Dan Hicks and Dick Bains, both of IBM Rochester, created a new product. The new product was a Pascal compiler that ran on IBM System/38. The Pascal language was first defined by Nicklaus Wirth in the 60's - I have the book. The Pascal language has some features that couldn't be implemented using the existing System/38 programming model so Dan and Dick had to create an extensive run-time environment for it. In other words, a new virtual machine that ran Pascal programs. The new run-time environment was called EPM - I seem to recall that EPM stood for "extended program model" and included such things as a stack to pass parameters and a heap to dynamically allocate storage. Simon says that EPM is dead and gone. Good. It was supposed to be a technology demonstration but someone decided to sell it. BTW, later, Fortran and C will added to EMP. By then, its tawdry past had caught up to it but it was too late to fix EPM. ILE was the solution and ILE really required new hardware to support it and so forth. So, Paul Remptema took on the job of coordinating the creation of ILE in the OS and coordinating with Toronto for the ILE languages. I don't know if Paul ever got credit for his contribution. We all owe Paul a debt for that job. I don't think that ILE was built from the original program model/architecture that Bains described in the early 1970s but they ended up being much alike.

Did they 'invent' Pascal? If so it must have really taken off, 'cause I studied it in an AP Computer class in high school in 83/84.
