-
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 VINFORMAT 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.
VINFORMAT returns the complete informat name, which
includes the width and the period (for example, $CHAR20.).
-
VINFORMAT returns the informat that is associated
with the specified variable. VINFORMATX, however, evaluates the argument
to determine the variable name. The function then returns the informat that
is associated with that variable name.
-
VINFORMAT does not accept an expression as an
argument. VINFORMATX 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, type, and length, among others. For
a list, see the "Variable Information" functions in Functions and CALL Routines by Category
