3.4.1. Introduction

NICHL (pronounced either N-I-H-C-L or "nickel") implements abstract data types that have been designed to simplify object-oriented programming using C++. It contains generally useful data types, such as String, Date, and Time, and it provides a set of classes similar to the Smalltalk 80 collection classes including OrderedCltn (indexed arrays), LinkedList (singly linked lists), Set (hash tables), and Dictionary (associative arrays).
