#### 7.7.5 Set-Membership Functions

Set membership functions determine whether a value is a member of a set. They take a set of numeric arguments or a set of string arguments, and produce Boolean results.

String comparisons are performed according to the rules given in Relational Operators.

— Function: ANY (value, set [, set]...)

> Results in true if value is equal to any of the set values. Otherwise, results in false. If value is system-missing, returns system-missing. System-missing values in set do not cause `/NAME/` to return system-missing.

— Function: RANGE (value, low, high [, low, high]...)

> Results in true if value is in any of the intervals bounded by low and high inclusive. Otherwise, results in false. Each low must be less than or equal to its corresponding high value. low and high must be given in pairs. If value is system-missing, returns system-missing. System-missing values in set do not cause `/NAME/` to return system-missing.
