Syntax

VINARRAY(variable)

Required Argument

variable

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

RestrictionYou 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 SAS Functions and CALL Routines by Category.

Example

The following SAS statements produce these results:
SAS Statement
Result
array x(3) x1-x3;
y=vinarray(x);
Z=vinarray(x1);
put y=;
put Z=;
 
y=0
z=1
