News from the SPSS Community

[Jon K Peck]

There are three updates on the SPSS Community website (www.ibm.com/developerworks/spssdevcentral).

Apropos of the recent discussion about finding empty variables, the FindEmptyVars function in spssaux2.py has been rewritten for better performance.  The old implementation passed the cases through the Python process and stopped as soon as it could prove that variables are not empty (as little as one case).  The new version uses AGGREGATE, which passes cases significantly faster but has to pass the entire dataset.  The file is in the Utilities Collection.

The SPSSINC MODIFY OUTPUT extension command has been updated with a new keyword to control whether page breaks are inserted for the first selected item or not.  This keyword is currently only available in syntax.  Use SPSSINC MODIFY TABLES /HELP for details.  The command is in the Extension Commands Collection.

The SPSSINC MODIFY TABLES extension command customstylefunctions.py module has been updated with a function named generic that provides extended access to the scripting apis without requiring anyone to write a new custom function.  For details, see the comments in customstylefunctions.py.  The command is in the Extension Commands Collection.
