   single: G7 New; For 2007
   
*G7*: New for 2007
===============================

We summarize here the work on a variety of extensions to *G7* that were completed in 2007, along with a number of other improvements. The work leaves *G7* more reliable and powerful, simultaneously lessening the burden on the model builder while extending his capabilities. In addition, these *G7* help files and the `G7 Reference Manual <http://inforumweb.inforumecon.com/software/g7.html>`_ have been extended and updated. This new documentation better reports the capabilities of *G7* and guides the model builder through difficult steps of data development. Please find a full report on recent improvments written by Ronald Horst, entitled `IT at Inforum in 2007 <http://inforumweb.inforumecon.com/organization/conferences/iwcxv/iwcxv.html>`_, on the `Inforum web site <http://inforumweb.inforumecon.com>`_. 

Improvements include: 

- New regression tools for Industry Data: the *eqpunch*, *ipch*, *tpch*, *punch*, and *titpch* commands.

- New *G7* Functions: *@if*, *@yoy*, *@ggr*, *@min*, *@max*, *@qchwt*, and *@pchwt* functions.

- An extention to the *vf* command: new inline date capability.

- Saving text: now append text to file with the *catch* and *save* routines.

- Dumping data: new options for the *matty* and *save* commands to print data as text in compact formats.

- Creating series from spreadsheet input: an extension to *G7*'s spreadsheet interface.

- Incremental adjustment of dates: extensions to the *fdates* routine and *limit* routine.

- Error handling: new capabilities for the user to manage errors.

- More arguments: the maximum number of arguments for the *do* loop, *add* command, and other routines has been increased.

- Table displays: Specify parameters to control the display of data in the *show* command window.
