To specify one or more scenarios for an analysis parameter (or set of parameters), you provide a list of values for the statement option that corresponds to the parameter(s). To identify the parameter you want to solve for, you place missing values in the appropriate list.

There are five basic types of such lists: keyword-lists, number-lists, grouped-number-lists, name-lists, and grouped-name-lists. Some parameters, such as the direction of a test, have values represented by one or more keywords in a keyword-list. Scenarios for scalar-valued parameters, such as power, are represented by a number-list. Scenarios for groups of scalar-valued parameters, such as group sample sizes in a multigroup design, are represented by a grouped-number-list. Scenarios for named parameters, such as reference survival curves, are represented by a name-list. Scenarios for groups of named parameters, such as group survival curves, are represented by a grouped-name-list.

The following subsections explain these five basic types of lists.
