The COMIT Feature in LISP II

Unknown author (1965-02-01)

The purpose of COMIT feature is to facilitate certain types of list manipulations in LISP II. This feature is a syntactic convenience, rather than an extension of the semantics of LISP. It permits the programmer to test directly whether a piece of list structure matches a certain pattern, and if so, to construct another structure utilizing subsegments of the original structure which matched parts of the given pattern.
