QPL Reference Manual

One of the design goals for QPL6 was to make the questionnaire program the only file you need to edit to create your web site and analysis files. The QPL system will now always rebuild your entire web site after you make a change to your program and recompile the files. Another goal was to make it easier to write and read your program. To meet these goals, the syntax for a number of QPL commands has changed.

New command key words have been added to to replace old option codes (that were often used as the first character in the first line of text for a question), and new key words have been added to automate formerly manual tasks, such as putting content into your project home page.

This page provides a number of before-and-after examples of how these features were programmed in QPL5 and how the same effect is achieved in QPL6.
