Questionnaires can be defined in SCROLL using the graphical interface. They can also be defined in a text file using the underlying CAWI scripting language which is documented in this section.
The scripting language has powerful programming features such as loops and list manipulation which may be needed for more complex questionnaires. The user is able to move easily between the graphical interface and editing the scripting file.
Note that not all accounts will have access to the script editing facility.
