var
-
specifies a variable that is expressed as
a scalar or as an array reference.
Restriction: |
You cannot use an
expression as an argument. |
-
VINFORMATW returns the informat width that is
associated with the specified variable. VINFORMATWX, however, evaluates the
argument to determine the variable name. The function then returns the informat
width that is associated with that variable name.
-
VINFORMATW does not accept an expression as an
argument. VINFORMATWX 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
