Hy! If I try to compile fortran 77 code with gfortran it gives the following error: In file simplex0d_red_stat.f:299 Included at ketir_keret_reda.f:1 9001 format(i8,<np>e16.8) 1 Error: Unexpected element in format string at (1) In file simplex0d_red_stat.f:294 Included at ketir_keret_reda.f:1 write(iout,9001)isc,xkiir 1 Where np is a parameter. What is the problem with format specification? Thanks, Atis __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
