Hi,

Here is my problem.

In OPL, I declare a set of tuple like...

tuple T{
string A;
int B;
};
{T} SET_of_T=...;

Also, in OPL, I declare array.

int Result[T];
Now, I have a scripting that I would like to assign a value B to array Result.

execute{

for (i in T)
Result[i]= ??????????????
};
};

The questio is what should I put in in the ????????????. I want Result[i]= B, where B is in the tuple of i. Note that I simplies the problem so that it is easy and breif enough to explain. In my actual model, I need to do some calculations, and if-then statement in my script block. I am stuck at how to assign a value in a set to an array.

thanks!

Hi Boon

In your case , I would not use a script to fill Result, but rather :

int Result[t in setofT] = t.B;

However, if you actually need a script, this would stand as :

int Result[setofT];
execute{
for(var t in setofT)
   Result[t] = t.B; 
}

Hope this helps
