VINARRAY Function

VINARRAY Function

Returns a value that indicates whether the specified variable is a member of an array

Category: Variable Information

Syntax

VINARRAY ( var )

Arguments

var

• specifies a variable that is expressed as a scalar or as an array reference.

• Restriction: You cannot use an expression as an argument.

Details

VINARRAY returns 1 if the given variable is a member of an array; it returns 0 if the given variable 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' on page 270.
