Version 0.3.0 changes since 0.2.3:
Bugs fixed:
* Using alphanumeric variables in functions under AGGREGATE
segfaulted. Fixed.
* Under certain circumstances, the final case would be omitted
from the results of an AGGREGATE operation. Fixed.
* Undefined behavior was invoked by referencing a freed pointer
under certain circumstances. Fixed.
* A wrong record size was displayed when paging the active file to
disk. Fixed.
* Not having enough temporary space for sorting caused a core
dump. Fixed.
* Syntax errors in function descriptions on AGGREGATE caused core
dumps. Fixed.
* A null pointer was dereferenced, causing a core dump, when
PERCENTILES was specified on FREQUENCIES. This fixes the
problem, but PSPP still doesn't calculate percentiles.
* SORT always sorted in ascending order. Fixed.
* Some minor memory leaks in the expression parser were removed.
* Many assertions fixed for strict ANSI C compliance.
New features:
* SET ECHO ON now implemented, but turned off by default.
* PRINT specifier supported on END REPEAT.
Other:
* System libgmp2 library is used if installed instead of
unconditionally using the included libgmp2 subset.
* Extensive code cleanup, which continues.
* Added CORRELATIONS command parser, but not implemented.

+
|
|
+ To have a long-named option do something other than set an `int' to
|
|
+ a compiled-in constant, such as set a value from `optarg', set the
|
|
+ option's `flag' field to zero and its `val' field to a nonzero
|
|
+ value (the equivalent single-letter option character, if there is
|
|
+ one). For long options that have a zero `flag' field, `getopt'
