Later, Paul Rovner and others at DEC SRC designed Modula-2+ (a l= anguage extension with exceptions, threads, garbage collection, and runtime= type dispatch). The Modula-2+ compiler was originally based on Powell=E2= =80=99s compiler. Modula-2+ ran on the VAX.

Here= =E2=80=99s a DEC SRC research report on Modula-2+:

Modula-3 was designed at DEC SRC and Olivet= ti Labs. It had a portable implementation (using the GCC back end) and ran = on a number of machines including Alpha.
