Hello
I have some code akin to this:
In[261]:= list1 = Table[Null, {j, 1, 5}];
For[i = 1, i <= 5, i++,
list1[[i]] := some_list[[i]];
]
Which after its execution will have list1 filled with these references:
{some_list[[6]], some_list[[6]], some_list[[6]], some_list[[6]],
some_list[[6]]}
But I would like the list to be filled with:
{some_list[[1]], some_list[[2]], some_list[[3]], some_list[[4]],
some_list[[5]]}
In other words, I would like the assignment of "i" to be immediate, but the assignment of some_list to be delayed, as the list will be updated periodically.
How do I achieve this? Thanks in advance.
