The new, Java-based interface makes SPSS even easier to use.
You can instantly resize dialog boxes to accommodate long variable
names and lists, and quickly drag and drop variables from one pane
to another to set up your analysis.

This interface also supports Unicode, so that you can work with data
in multiple languages from a single application. You can treat text data
according to Unicode properties for tasks like sorting and case conversion.

Also, through the SPSS Programmability Extension, an SPSS Integration
Plug-In for R is available. This enables users to access the wealth of
statistical routines created in R and use them within SPSS as part of
SPSS syntax. An SPSS Programmability Integration Plug-in provides the
crucial link and configuration instructions that enable an SPSS syntax job
to take advantage of a specific external programming language or dynamic
link library (DLL). SPSS 16.0 includes many enhancements to data
management that users have specifically requested.

Reporting enhancements include a new, more powerful visualization engine,
which replaces the Interactive Graph Properties (IGRAPH) feature. This makes
graph editing faster and easier. (Existing IGRAPH syntax will continue to work.)
The enhanced Chart Editor delivers a similar level of functionality as
the previous IGRAPH editor.

In addition, SPSS 16.0 introduces Python as the default front-end scripting
language. Python supersedes SAX Basic as the scripting language for tasks
such as automation of repetitive tasks and customization of output.
(Existing SAX Basic scripts will continue to work in SPSS 16.0.)
