The AUTOMATIC attribute specifies that storage for the  variable
  be  allocated  each time the program enters the routine in which
  the variable is declared.  The storage is deallocated each  time
  the  program  exits  from  that  routine.  An automatic variable
  exists as long as the declaring routine remains active.

  See the "HP Pascal Language Reference Manual" for  the  complete
  description of using the AUTOMATIC attribute.
