Hi,

I used IBM ILOG CPLEX Optimization Studio to run a  problem, but got an error with messy code. The file editor didn't alert any errors until I pushed the run button.

The error is:

ÔËÐÐÅäÖá°option 1¡±²»´æÔڡ£          unknown OPL

As such an error, I really don't know how to fix it. Here is the .mod and .dat file.

 .dat file

Do my codes have any mistakes? Or it is the reason that my cplex is Promotional version which limits at most 1000 constraints?

Can you please ask this question on the OPL Forum https://www.ibm.com/developerworks/community/forums/html/forum?id=11111111-0000-0000-0000-000000002053.

It seems an OPL expert is required.
