VFORMATX (expression)

Arguments

expression

specifies any SAS character expression that evaluates to a variable name.

Restriction:

The value of the specified expression cannot denote an array reference.

Details

VFORMATX returns the complete format name which includes the width and the period (for example, $CHAR20.).

Comparisons

VFORMAT returns the format that is associated with the specified variable. VFORMATX, however, evaluates the argument to determine the variable name. The function then returns the format that is associated with that variable name.
VFORMAT does not accept an expression as an argument. VFORMATX 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, length, and type, among others. For a list, see the "Variable Information" functions in Functions and CALL Routines by Category .
