;ERR3 IS CALLED WHEN AN ERROR IS FOUND IN THE INTERNAL DATA BASE
; OF THE FORTRAN COMPILER. ERR3 GENERATES A MESSAGE OF THE
; FORM:
; ?
; ? Internal compiler error processing statement nnnn
; ? Call to <entry> from xxxxxx
;
;IF DDT IS LOADED CONTROL TRANSFERS TO DDT.
;
;ALL AC'S AS RESTORED PRIOR TO EXIT FROM ERR3 AND THE STACK IS
; LEFT AT THE SAME DEPTH AS WHEN ERR3 WAS CALLED. SEVERAL LOCATIONS
; BEYOND THE END OF THE STACK ARE CLOBBERED. THERE ARE NO TEMPS AND
; ALL CODE IS IN THE HISEG.
