VINARRAYX Function

Arguments

expression

specifies a character constant, variable, or expression that evaluates to a variable name.

Restriction:

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

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.

• 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 .

array x(3) x1-x3;
array vx(4) $6 vx1 vx2 vx3 vx4
   ('x' 'x1' 'x2' 'x3');
y=vinarrayx(vx(1));
z=vinarrayx(vx(2));
put y=;
put z=;

y=0
z=1
