  • a large, coherent, integrated collection of intermediate tools for data analysis,

  • graphical facilities for data analysis and display either on-screen or on hardcopy, and

  • a well-developed, simple and effective programming language which includes conditionals, loops, user-defined recursive functions and input and output facilities.
