Hi guys, 

i have a model on opl  which doesn't work properly and i am trying to trace the problem, but it is not so easy. A friend suggested that i need to find a way to extract a lp file,  but still the interpretation of the results  is hard, since the names of the variables looks strange. I am wondering if there is any way  to initialiaze names of the variable (strings) on the lp,  in order to debug the code. I know that you can do something like that on java but i am not sure what is happening with opl. Do u have any advice/ tutorial/ example that can help? 

Regards. 

Hi,

do you know that in the IDE you have a pretty nice debugger as can be seen in documentation

IDE and OPL > CPLEX Studio IDE > IDE Tutorials > Using IBM ILOG Script for OPL > The multiperiod production planning example

or

The name of the variables in the lp may look strange because you reached the label threshold

You may change this

regards
