─────AUTOMATIC──────────────────────────────────────────────────────────────
 
     Action
 
     Declares specified variables on the stack, rather than at a static
     memory location.
 
     Syntax
 
     AUTOMATIC [names]
 
     Parameter          Description
 
     names              A list of variables or array names to be made
                        automatic. Separate multiple names with commas.
 
     Remarks
 
     All variables are static by default.
 
     If an AUTOMATIC statement contains no variable names, all the
     variables within that program unit that can legally be automatic are
     implicitly automatic.
 
     Common-block names and variables are not allowed in an AUTOMATIC
     statement. A variable cannot appear in both a SAVE statement and an
     AUTOMATIC statement.
 
     Variables with the ALLOCATABLE, EXTERNAL, FAR, or HUGE attribute
     cannot be automatic. Formal arguments may not be declared automatic.
 
     A variable that has been explicitly declared automatic may not
     appear in a DATA or EQUIVALENCE statement. Variables that are
     implicitly automatic and appear in a DATA statement will be
     initialized and placed in static memory. A variable may appear
     in an AUTOMATIC statement only once.
 
     Formal arguments and procedure names may not appear in an
     AUTOMATIC statement.

     Example
 
     C     In this example, all variables within the program unit
     C     are automatic, except for "clark" and "lois"; these are
     C     explicitly declared in a SAVE statement, and thus have
     C     static memory locations:
 
           INTEGER FUNCTION  Fibonacci (clark, lois)
           AUTOMATIC
           SAVE  clark, lois
           ...
           END
