Fortran runtime error: Bad real number in item 1 of list input. Can you help me, What is problem?

Very simple
                   B=0.0
                   DO 10 I=1,3
                   READ*,A
                   B=B+A
            10   CONTINUE
                   PRINT*,B
                   END

This forum is primarily for users of Absoft Fortran. Your error message came from the gfortran runtime library. I would suggest trying a gfortran forum for support on this question.
