VFORMATDX Function

Arguments

expression

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

Restriction:

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

• VFORMATD returns the format decimal value that is associated with the specified variable. VFORMATDX, however, evaluates the argument to determine the variable name. The function then returns the format decimal value that is associated with that variable name.

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

array x(3) x1-x3;
format x1 comma8.2;
array vx(3) $6 vx1 vx2 vx3
   ('x1' 'x2' 'x3');
y=vformatdx(vx(1));
z=vformatdx('x'||'1');
put y=;
put z=;

y=2
z=2
