UBC in 1988. Trilogy is syntactically a blend of
variables), procedures (if-then-else but no backtracking;
assignable variables), and
subroutines (like procedures, but

system calls; callable only from top level or
from other subroutines).
Development of Trilogy I stopped in 1991. Trilogy II,
developed by Paul Voda 1988-92, was a
declarative general
purpose programming language, used for teaching and to write
["The Constraint Language Trilogy: Semantics and
Computations", P. Voda, Complete Logic Systems, 741 Blueridge
Ave, North Vancouver BC, V7R 2J5].
