      SUBROUTINE E9RINT(MESSG,NW,NERR,SAVE)
C
C  THIS ROUTINE STORES THE CURRENT ERROR MESSAGE OR PRINTS THE OLD ONE,
C  IF ANY, DEPENDING ON WHETHER OR NOT SAVE = .TRUE. .
C
C  CHANGED, BY P.FOX, MAY 18, 1983, FROM THE ORIGINAL VERSION IN ORDER
C  TO GET RID OF THE FORTRAN CARRIAGE CONTROL LINE OVERWRITE
C  CHARACTER +, WHICH HAS ALWAYS CAUSED TROUBLE.
C  FOR THE RECORD, THE PREVIOUS VERSION HAD THE FOLLOWING ARRAY
C  AND CALLS -   (WHERE CCPLUS WAS DECLARED OF TYPE INTEGER)
