For example, you may specify that one variable will appear with each of its values as a separate row in your table and that another variable will appear as a column of its mean values. When all variables have been selected, defined, and placed as rows or columns, select the Save option from the File menu. The DAS then produces a text file that contains the information, or parameters, used to compute the request. There are Categorical and Continuous variables in every DAS system. A few categorical variables may have special or restricted code values of zero.
Continuous variables are additive.
The above variables may not be in the DAS you are using. The DAS system allows you to specify all of these elements. The text may NOT extend beyond the table's column headings. Subsequent lines must be indented to match the beginning of the text on the initial title line. Title lines are input by you when you save the parameter file .
