Returns the format name that is associated with the value of the
specified argument.

Variable Information
|
-
expression
-
specifies a character constant, variable,
or expression that evaluates to a variable name.
Restriction: |
The value of the
specified expression cannot denote an array reference. |
If the VFORMATNX 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.
VFORMATNX returns only the format name, which does not
include the length or the period (for example, $CHAR).
-
VFORMATN returns the format name that is associated
with the specified variable. VFORMATNX, however, evaluates the argument to
determine the variable name. The function then returns the format name that
is associated with that variable name.
-
VFORMATN does not accept an expression as an argument.
VFORMATNX 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
