VFORMATW returns the format width that is associated
with the specified variable. VFORMATWX, however, evaluates the argument to
determine the variable name. The function then returns the format width that
is associated with that variable name.

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