VLABELX Function

Returns the variable label for the value of the specified argument

Category: Variable Information

VLABELX ( expression )

expression

specifies any SAS character expression that evaluates to a variable name .
Restriction: The value of the specified expression cannot denote an array reference.

If the VLABELX 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, VLABELX 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.
Related functions return the value of other variable attributes, such as the variable name, informat, and format, among others. For a list, see the 'Variable Information' functions in 'Functions and CALL Routines by Category' on page 270.
