I think the best approach for the solving successively with the simplex method is to use glp_get_row_stat()/glp_get_col_stat() and glp_set_row_stat()/glp_set_col_stat().
Does this make sense?
Try glp_save_mps to save the basis and and glp_read_mps to load the warm-start..
Depending on what you are trying to do, you may wish to use a solver which can understand XML. This can be edited outside of the solver, and hence the problem can be modified and solved without programming. Of course MPS is text based and you could try to edit it (I wish you good luck).
I am currently considering an example of combining five constraint matricies to produce a single solution. As pointed out in earlier communications you need rules for the combination. When the CMs are in XML then XLST provides a way to provide the rules.
