OBJSENSE is a non-standard feature of MPS format. Please see
(IBM OSL can be considered as a relevant reference due to its
compatibility with IBM MPS/360 and MPSX/370.)

Please note that it is always possible to change the objective sense
either with the routine glp_set_obj_dir (on api level) or with options
--min/--max (on using glpsol).

Best regards,
