Use an indexed parameter:

In your model section declare:

set IdxWeeks;
param weeks[IdxWeeks];

and in your data section have:

param : IdxWeeks : weeks :=
 1  1
 2  4
 3  8
 4  11

I have a discrete set.

set weeks:={1,4,8,11};

What I want to do is create a parameter to access the i-th element of the set.
weeks[1] = 1, weeks[2] = 4, weeks[3] = 8 and weeks[4] = 11.

I want to do this assignment dynamically because these week numbers will change 
each time new data is entered into the model.

Do you have any suggestions or code?
