VINFORMATDX Function

Arguments

expression

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

Restriction:

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

• VINFORMATD returns the informat decimal value that is associated with the specified variable. VINFORMATDX, however, evaluates the argument to determine the variable name. The function then returns the informat decimal value that is associated with that variable name.

• VINFORMATD does not accept an expression as an argument. VINFORMATDX 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, length, and type, among others. For a list, see the "Variable Information" functions in Functions and CALL Routines by Category .

informat x1 x2 x3 comma9.3;
input x1 x2 x3;
array vx(3) $6 vx1 vx2 vx3
   ('x1' 'x2' 'x3');
y=vinformatdx(vx(1));
put y=;

y=3
