Example 1: VAR in Banner Logic:
This example shows how a banner column can represent a response base, such as rating scale, rather than the traditional respondent base. The logic used in this example results in the following table:

Because the variable is in the banner column, the row logic is used as the starting point. Each banner column uses the row logic plus the VAR number.

Because the variable is in the row, the banner logic is used as the starting point. Each row uses the banner logic plus the VAR number.
Similar to the 'Total' column, the table filter can represent a response base, rather than a respondent base. The logic for the table filter when the variables are in the rows is VAR+ followed by the range of variables for that table.
Example 3: Using VAR With Other Logic:
If any row of the table must be based on a secondary criterion you can include the additional logic after the VAR instruction.
VAR+1 AND GENDER (1)
Example 4: Using [+] With VAR to increment logic
You can use [+] with VAR to increment banner, row and filter logic elements. Any logic surrounded by [+] is incremented by the VAR instruction. For example, if the logic for banner point 3 is:
VAR+5
and the row definition is:
[+]Q5A (5) AND Q3_1 (2)[+]
then the banner point with VAR+5 references:
Q5F (5) AND Q3_6 (2)
Example 5: Using [X] With VAR to exclude logic from incrementing
You can use [X] with VAR to exclude banner, row and filter logic elements from being incremented. Any logic surrounded by [X] is excluded. For example, if the logic for banner point 3 is:
VAR+5
and the row definition is:
[+]Q5A (5) AND [X]Q12 (2)[X] AND Q3_1 (2)[+]
then banner point three references:
Q5F (5) AND Q12 (2) AND Q3_6 (2)
the Q12 (2) does not get incremented
