Fortran 95 question about dimension error

  1. Jul 16, 2011 #1
    error 542, J appears in the dimension of a variable,yet is not a dummy argument,a variable available through USE or CONTAINS association,a COMMON variable,a PARAMETER,or a PURE FUNCTION
    the same error about I
    i am using i,j in order to point the temperature in length and time T(i,j)
    it is a numerical solution for the heat diffusion equation that uses the previous and the next value according to length of temperature and the previous value of temperature according to time( Crank-Nicolson method)

    It's going to be hard to troubleshoot your program without a listing.
