Computer Languages for Symbol Manipulation
Bert F. Green · IRE Transactions on Electronic Computers · 1961
Complex, flexible, computer programs can be written easily in list-processing languages. Storage registers are linked together in arbitrary sequences to form lists and list structures, which are the units of the languages. Special provisions are made for recursive subroutines and for hierarchical programs. These particular languages have been used to write game-playing, problem-solving, and other ``intelligent'' Programs.
