P-STAT 3.01 revision 8

P-STAT Version 3.01 revision 8 is the latest release. It is available for PC/Windows, Linux and Solaris. This revision augments the use of wildcard references in KEEP phrases.

Progress has been made on reading huge files in P-STAT on a windows PC. Huge means more than 2.147 billion bytes. P-STAT can now read such a file, but slowly, one byte at a time. Reading a 2.6 billion file takes 5 minutes or so.

P-STAT 3.01 revision 6

This revision fixes several errors in the earlier revisions and has a significant change in the use of abbreviations in PPL and in the use of wildcards.

TURF: has a new option which uses the full (64-char) varnames to identify combinations in the reach.results and freq.results files. This option is selected by using the identifier FULL in the TURF command. An error in the PC menu code for TURF has also been fixed.

MACROS: An error in the insertion macros code which caused a message about 'vnames' has been fixed.

SURVEY: A survey command which failed to print the percent fields when there were more that 92 banner points and many statistics has been fixed.

CHECK: The check command had problems reading a Version 2 system file. This problem has been fixed.

SPSS.OUT: This command worked the first time it was used in a run but failed if it was used a second time.

ABBREVIATIONS: which were not allowed in version 2 but had been allowed in version 3 before this revision have been dropped because they too often cause unexpected matches. Wildcards (?) add safeguards that make it easy to use short names.

If there is only one variable name that starts with "income", using income? has the same effect as an abbreviation. In addition wildcards are more powerful because they can be used anywhere in a string. For example a variable name that starts with "income" and ends with a year, income??2007 would only match a name that starts with "income" and ends with "2007".

ABBREVIATIONS in SURVEY subcommands: There is one exception. In version 2, SURVEY subcommands allowed abbreviations. This sometimes caused a conflict between variable names and other SURVEY subcommands. Abbreviations here are still allowed but conflicts can be avoided by using wildcards instead.

The maximum path and filename has been increased from 160 to 200.
