VINARRAYX (expression)

Arguments

expression

specifies any SAS character expression that evaluates to a variable name.

Restriction:

The value of the specified expression cannot denote an array reference.

Details

VINARRAYX returns 1 if the value of the given argument is a member of an array; it returns 0 if the value of the given argument is not a member of an array.

Comparisons

VINARRAY returns a value that indicates whether the specified variable is a member of an array. VINARRAYX, however, evaluates the argument to determine the variable name. The function then returns a value that indicates whether the variable name is a member of an array.
VINARRAY does not accept an expression as an argument. VINARRAYX accepts expressions, but the value of the specified expression cannot denote an array reference.
Related functions return the value of other variable attributes, such as the variable name, informat, and format, among others. For a list, see the "Variable Information" functions in Functions and CALL Routines by Category .
