   PSPP now reads and writes system files compatible with spssV12.  
   
   New commands:   VARIABLE WIDTH, VARIABLE ALIGNMENT, VARIABLE LEVEL.

32        * SORT CASES now sorts stably, that is, two cases with equal sort
33          criteria will be in the same relative order before and after the
34          sort.

38      * USE (as a stub, to enhance compatibility).      * DATE and USE.  These commands are parsed but otherwise ignored,
39          to enhance compatibility with certain command files that invoke
40          them unnecessarily.
41    
42        * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL.  These
43          currently have no effect on PSPP output, but their values are
44          written to and read from system files and thus may affect
45          third-party software.
46    
47        * SET EPOCH implemented.
48    
49        * DATA LIST FREE and DATA LIST LIST now support arbitrary field
50          delimiters.
51    
52        * FILE HANDLE now supports custom tab widths.
53    
54      Long variable names (and other identifiers) are now supported.  Up
55      to the first 64 bytes of each identifier is significant.  PSPP now
56      reads and writes system files compatible with SPSS version 12.
