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 struct concept in C. Beads could be strung into plexes to build composite data structures.
