A programming language developed at MIT
by Douglas T. Ross and associates. Its TLA had a dual interpretation:
Automated Engineering Design language or Algol
Extended for Design. It added pointer variables, dynamic
allocation, and beads
which anticipated the
concept in C. Beads
could be strung into plexes to build composite data structures.
