I think that if the table driver routine encounters a null value, it would be sufficient just *not* to call mpl_tab_set_num/str, in which case dca->type[k] being initialized to '?' will not be changed and cause an error. _______________________________________________ Bug-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/bug-glpk
