CPXERR_EXTRA_FR_BOUND
1455 Line %d: 'FR' bound type illegal when prior bound given.
      
 A column with an upper or lower bound 
 previously assigned has an illegal FR 
 bound assignment. Since the FR bound 
 type has neither an upper nor lower bound, 
 no other bound type can be specified. Check the MPS file.
