Special conditions unique to the tabulation section are:
c=-

c=-n
Counts respondents eligible for inclusion in the axis who have not appeared in the last n elements.
c=+
Counts respondents in any of the elements since the last base element.
c=+n

More information
There are some special condition statements that can be used to accumulate counts of respondents on the basis of whether or not they have been included in any, or a specified number of, elements since the last base in the axis.
The following special condition statements are often used to deal with Don’t Knows and No Answers when there are no specific codes for these responses. They consider respondents to be eligible for inclusion in the axis if they meet the conditions on the l statement; they ignore any conditions on n10 and n11 statements:
c=-
Counts all respondents eligible for inclusion in the axis who have not been included in any element since the last base element.
c=-n
Counts respondents eligible for inclusion in the axis who have not been included in the previous n elements.
The following special condition statements are often used to create ‘net’ elements in axes for questions with multiple choice or open end responses:
c=+
Counts respondents included in any of the elements since the last base element.
c=+n
Counts respondents included in the previous n elements.
These special condition statements stop counting if they encounter one of the following elements in the axis:
▪a base element
▪an nsw element, which Quantum inserts after each base element in axes in weighted runs that request special T statistics
▪an effbase element, which you can use to print an effective base element in a weighted table. If you want to print an effective base without affecting the processing of these special statements, use an n31 statement.
