;  Comment--this is an  alternate  initial  start  address  to  get
;  around  a  bug  in  LINK-10.   It  deletes  the  symbol table by
;  changing the JOBDAT parameters so that the SAVE command will not
;  save it.  This is done because LINK will not a generate a symbol
;  file without leaving the  symbols  in  core.   To  perform  this
;  chicanery,  use  the /START:SSTART/EXECUTE switches when linking
;  SOS.  The normal start address, SOS, will be  installed  by  the
;  code that follows.
