Well, maybe you should have tested it too :-).  Anyhow here is a slightly
hacked version which does work-- not 18 lines though, more like 22 (I made
C into a character array since that worked better with f77 on a big-endian
3B).

      IMPLICIT INTEGER (A-Z)
      INTEGER A(10,10), B(10,10)
      CHARACTER C(10,10)
      DATA A /100 * 0/
      READ(5,10)((A(I,J),J=2,9),I=2,9)
10    FORMAT(8I1)
      DO 100 COUNT = 1,50
      DO 50 I = 2,9
      DO 50 J = 2,9
      SUM=A(I-1,J-1)+A(I-1,J)+A(I-1,J+1)+A(I,J-1)+A(I,J+1)
     >+A(I+1,J-1)+A(I+1,J)+A(I+1,J+1)
      B(I,J)=0
50    IF((SUM.EQ.3).OR.((SUM+A(I,J)).EQ.3))B(I,J)=1
      DO 60 I=2,9
      DO 60 J=2,9
      C(I,J) = ' '
      IF (B(I,J).EQ.1)C(I,J) = '*'
60    A(I,J) = B(I,J)
100   WRITE(6,70)COUNT,((C(I,J),J=2,9),I=2,9)
70    FORMAT('  Gen ',I3,/,2X,8('*'),/,8(' |',8A1,'|',/),2X,8('*'),/)
      STOP
      END
