Hello,

I have a question in OPL script, I would like to declare a vector of integer in a main script block (or an execute) is it possible?

I usually declare such arrays and a fixed size in preamble, but it is not possible in my case, because the size of the vector change..

Do you have a solution?

If I declare it in a function, is it a local variable that is suppressed after the end of the function?

Thanks,

Hi,

in scripting  when an element of an array is set beyond the current length of the array, the array is automatically expanded.

main
{
 var a=new Array(1);
 a[1]=2;
 writeln(a.length);
 a[5]=4;
 writeln(a.length);
}

gives

2

6

You should have a look at
