+@cindex @code{AUTOMATIC}
+@cindex @code{STATIC}
+
+With @option{-fdec-static} GNU Fortran supports the DEC extended attributes
+@code{STATIC} and @code{AUTOMATIC} to provide explicit specification of entity
+storage. These follow the syntax of the Fortran standard @code{SAVE} attribute.
+
+@code{STATIC} is exactly equivalent to @code{SAVE}, and specifies that
+an entity should be allocated in static memory. As an example, @code{STATIC}
+local variables will retain their values across multiple calls to a function.
+
+Entities marked @code{AUTOMATIC} will be stack automatic whenever possible.
+@code{AUTOMATIC} is the default for local variables smaller than
+@option{-fmax-stack-var-size}, unless @option{-fno-automatic} is given. This
+attribute overrides @option{-fno-automatic}, @option{-fmax-stack-var-size}, and
+blanket @code{SAVE} statements.
+
+
+Examples:
+
+@example
+subroutine f
+ integer, automatic :: i ! automatic variable
+ integer x, y ! static variables
+ save
+ ...
+endsubroutine
+@end example
+@example
+subroutine f
+ integer a, b, c, x, y, z
+ static :: x
+ save y
+ automatic z, c
+ ! a, b, c, and z are automatic
+ ! x and y are static
