Group FileFor every dynamic variable there must be a group file that defines the categories. The group file must be in the same location as the configuration file. When using a dynamic variable the CGI looks for a group file that has the exact same name (html_name from the configuration file, name used in the xml file) as the dynamic variable. It uses the group file to group the values in the corresponding SAS variable.
A dynamic variable is defined in the configuration file by setting the type2=3. See the age variables in the example configuration file.
Note: To use a dynamic variable the SAS dataset values need to be continuous (ungrouped); for example, single years of age or single years.
