PASW Statistics analytical engine through an application program interface (API). APIs provide programs with: 3 Direct access to the active dataset 9s variables, variable properties and attributes (name, format, labels, measurement level, type, and user-defined attributes), case count, and case data 3 Access to an in-memory, XML version of the data dictionary and procedure output 3 An XPath evaluation engine that allows access to and navigation of the in-memory XML workspace 3 A method for queuing and executing command syntax 3 Direct access to the last error code and message n Develop your own procedures 4 including those for statistical analyses not included in PASW Statistics 3 Define new syntax in PASW Statistics style via an XML schema and have PASW Statistics handle parsing and error checking 3 The procedure can send results into an PASW Statistics pivot table or into text blocks 4 essentially extending the analytical capabilities of PASW Statistics Benefits n Extend PASW Statistics functionality.<br><br> The PASW Statistics Programmability Extension enables you to add functionality not included in PASW Statistics Modules. n Write generalized and more flexible jobs. Create generalized jobs by controlling logic based on the Variable Dictionary, procedure output (XML or datasets), case data, and environment.<br><br> Reusable code means data are not tied to a single program. n Handle errors with generated exceptions. The PASW Statistics Programmability Extension makes it easy to check whether a long syntax job worked.<br><br> n React to results and metadata n Build PASW Statistics functionality into other applications Take advantage of procedures created and shared by other users through SPSS Developer Central How to get started 3integration plug-ins Since the PASW Statistics Programmability Extension is included with PASW Statistics, you can get started quickly. PASW Statistics Programmability Integration Plug-Ins are available online at SPSS Developer Central, www.spss.com/devcentral . This allows you to take advantage of this advanced programmability functionality immediately.<br><br> n Obtain server-side scripting through external languages 3 An open extension to the PASW Statistics backend enables you to write code using suitable external programming languages and include the code within production syntax jobs 3 Scripts execute at the location of your PASW Statistics processor. Depending on the type of system you are using, your scripts will execute on either the client or the server. If you execute scripts on PASW ® Statistics Server*, you can perform operations previously available only through client-side scripting.<br><br> Programming capabilities Combining backend processor APIs with an external programming or scripting language opens up a limitless set of new possibilities from within syntax jobs. For example, use the PASW Statistics Programmability Extension to control the flow of your command syntax jobs through conditional execution control statements (such as cIf/Then/Else d) and looping control statements (such as cFor d and cWhile d) found in the external programming language 9s syntax. Use scripts written in external programming languages to conditionally execute or make decisions about which syntax is executed based on a particular condition, such as: n The value of the variable attributes in the data dictionary n Values in the output n Values in the active dataset n Error-level return codes from PASW Statistics procedures In short, you can create reusable code that speeds the process of turning data into decisions.<br><br> Additionally, take advantage of all your external programming language 9s non-PASW Statistics-related capabilities in your scripts. For example, have a production job trigger an e-mail notification once your job has successfully completed. PASW Statistics Syntax Job Flow Command 1 Check state of dictionary, output, or return code Command 2 Command 3 Pass Fail Control the flow of your PASW Statistics syntax jobs.<br><br> In this example, command 1 is executed. Then, if the dictionary, output, or return code passes, command 2 is performed. If it fails, command 3 is performed instead.<br><br> * PASW Statistics Programmability Extension, PASW Statistics, and PASW Statistics Server, formerly called SPSS Programmability Extension, SPSS Statistics, and SPSS Statistics Server , are part of SPSS Inc. 9s Predictive Analytics Software portfolio.
