Released new version 10.2.

The SS option in banners has been enhanced. A digit may be added to SS=A or SS=D to sort the stub excluding the last one or last two value labels. This is useful when the last value label is an "other" or "don't know" category, and you want to sort the stub, but still leave the "other "or "don't know" as the last row on the stub. For example SS=D1 would sort the stub in descending order by frequency, except it would leave the last value label as the last row regardless of its frequency.

Added non-integer (fractional) weighting.

1/28/06 Four new features added to Internet surveys:
1) Added constant sum validity check to grouped text boxes.
2) Added validity check to grouped text boxes used for ranking.
3) Added validity check to require at least x checks in multiple response check boxes.
4) Added ability to delay a branch until respondent clicks the submit button.

2/24/06 Fixed problem setting permissions on when using AutoTransfer to upload files to the Web site.
2/28/06 Fixed problem in banners sorting stub with SS option when TY=P.

Modified Web surveys so you can change the name of to anything you want (except it must have a .pl extension). For example, if you are doing a survey for XYZ company, you might use a CgiBin setting like this:


That way, respondents will see the company name in their address bar while they are taking the survey. If you use AutoTransfer to upload the files to your server, StatPac will automatically rename to while uploading the file. If you manually upload the files to your server, then you need to manually rename the file on your server from to The important thing is that the name of the .pl file on your server is exactly the same as the CgiBin setting in the script. Unix/Linux servers are case sensitive, so make sure you use the same case for the file name.
