Since we are in historical mode...

The first version of Ada-ED was interpreting directly SETL structures. 
The second one generated code for a virtual machine.

If you are really interested, the description of the virtual machine can 
be found in the PhD thesis of P. Kruchten and J-P. Rosen ;-). Only 
available on paper, though (this was in 1985).
