There may be times when you need more complex definitions in table rows and/or columns, or in a banner, than you are able to define by nesting questions. For example, you may need a column header for a sub group of respondents defined by their combined responses to several questions. An example of this could be; males between 31 and 67 years who test-drove a Ford, Volvo or Chrysler, and who think safety is important or very important.
You can create two types of segment definitions; “standard” segments and expressions, and you can use two types of expressions; "standard" and TGL.
Note: The code used in standard segments and TGL segments is not interchangeable; you cannot use the TGL language in a standard segment expression or standard segment code in a TGL segment. However, you can use either type of segment to do the same job, and you can use both types of segment in the same report.
