g77 doesn't support the
AUTOMATIC statement that
AUTOMATIC would identify a variable or array
as not being
SAVE'd, which is normally the default,
but which would be especially useful for code that, generally,
needed to be compiled with the -fno-automatic option.
AUTOMATIC also would serve as a hint to the compiler that placing
the variable or array—even a very large array–on the stack is acceptable.
AUTOMATIC would not, by itself, designate the containing procedure
AUTOMATIC should work syntactically like
AUTOMATIC with no variables listed should apply to
all pertinent variables and arrays
(which would not include common blocks or their members).
Variables and arrays denoted as

or other specification of any initial values,
requiring explicit initialization,
such as via assignment statements.
