var
-
specifies a variable that is expressed as
a scalar or as an array reference.

If the VNAME function returns a value
to a variable that has not yet been assigned a length, by default the variable
is assigned a length of 200.
-
VNAME returns the name of the specified variable.
VNAMEX, however, evaluates the argument to determine a variable name. If
the name is a known variable name, the function returns that name. Otherwise,
the function returns a blank.
-
VNAME does not accept an expression as an argument.
VNAMEX accepts expressions, but the value of the specified expression cannot
denote an array reference.
-
VNAME has the same functionality as CALL VNAME.
-
Related functions return the value of other
variable
attributes, such as the variable label, informat, and format, among others.
For a list, see the "Variable Information" functions in
