This [the bit about DEC] seems to have been totally overlooked in the 'history' recorded at the AdaPower web-site. There the early development of an Ada 'compiler' is associated with New York University (NYU) and the Ada/Ed model (c1980). Do you have any references for the role of DEC? I am also unclear about just what these 'libraries' actually are; could you elaborate some more please? There seems to be a scarcity of information about this - even on the HP web-site (which still provides the supporting documentation for the DEC Ada product). [This includes their annotated Ada Language Reference Manual, which seems to be one of the few available electronic versions of the old Ada83 standard.] > As for the 'MIL-STD-1815' spec was created at the end of 1980. > But the design and first full language compiler was created in > 77 - 78 more than two years before.

That is true (and I don't think I claimed otherwise); the main history of Ada is quite readily available - this includes the roles of the STRAWMAN-STEELMAN documents, the four competing development teams Green, Red, Blue & Yellow. All these documents were published for review. (I think it is possible to find a commentary on Green by Dijkstra online). -- Stuart
