RS01163: CPLEX 12.5.0.0 CAN REJECT MPS FILE WITH CHARACTERS ASSOCIATED WITH ASCII CODES 128-255 (ATYPICAL ASCII CHARACTERS).

APAR status

• Closed as fixed if next.

Error description

• This only happens with 12.5.0.0.  MPS files with ASCII
  characters with code values of 128-255 will not be properly
  translated, resulting in error messages such as:
  
  
  CPLEX> Selected objective sense:  MINIMIZE
  Selected objective  name:  PROFIT
  CPLEX Error  1448: Line 7: '' is not a row name.
  No file read.
  
  
  Previous versions of CPLEX handled this with no trouble.
  
  
  RTC-14608
  

Local fix

• Use CPLEX 12.4.   If need 12.5 for performance, use 12.4 to
  input file, write out a .rew or SAV file to avoid the input
  of these characters, then input with 12.5.
  

Problem summary

• CPLEX 12.5.0.0 CAN REJECT MPS FILE WITH CHARACTERS ASSOCIATED
  WITH ASCII CODES 128-255 (ATYPICAL ASCII CHARACTERS).
  

Problem conclusion

Temporary fix

• Replace any non-7bit-clean character in your MPS file by a 7bit
  clean character.
