Hello Andrew, when a table IN statement mispells a column name glpk issues the following message GLPK internal error: dca->type[k] != '?'; file glpmpl03.c, line 4846
To analyze the error in the model it would be helpful to show the column name causing the problem. Best regards Xypron _______________________________________________ Help-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-glpk
