-
var
-
specifies a variable that is expressed as
a scalar or as an array reference.
Restriction: |
You cannot use an
expression as an argument. |
If the VLABEL 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.
If there is no label, VLABEL returns the variable name.
-
VLABEL returns the label of the specified variable
or the name of the specified variable, if no label exists. VLABELX, however,
evaluates the argument to determine the variable name. The function then returns
the label that is associated with that variable name, or the variable name
if no label exists.
-
VLABEL does not accept an expression as an argument.
VLABELX accepts expressions, but the value of the specified expression cannot
denote an array reference.
-
VLABEL has the same functionality as CALL LABEL.
-
Related functions return the value of
other variable
attributes, such as the variable name, informat, and format, among others.
