Earlier in this somewhat-long thread I asked:

Perhaps he is really complaining about the instruction set of a CPU or
processor architecture (the VAX), and not about a programming language
(Ada) at all. Note his assertion that "VAX" violated some alleged
design goal of Ada. Having tried unsuccessfully to discover his meaning
by direct questions, all I can conclude is that he is blaming the Ada
programming language (which he apparently thought was designed by DEC)
for the fact that the VAX is non-compliant with the Data General
instruction set!
