It mentions Forth briefly:
Even more troubling were reports of incredible software productivity
from US projects using languages like Lisp, APL, Prolog, Smalltalk and
Forth. Entire robotic planning systems with natural language and
graphics interfaces were programmed by just one or two people in
Lisp. Reams of PL/I code were replaced by a single line of APL. Prolog
obsoleted a generation of Cobol programmers. Smalltalk and Logo were
taught to children, and raised the spectre of a 12-year-old
outproducing a dozen beltway bandits. Perhaps most troubling of all
was Forth, with its ability to very quickly program substantial
real-time systems that took insignificant amounts of memory.
