Hi,
1)
in the following example len1 and len2 are assigned values.
In[2]=status = {len1, len2}
status1 = {3, 4};
{len1, len2} = status1;
Print["status: ", status];
Print["len1: ", len1, "  len2: ", len2]

Out[2]= {len1, len2}
status: {3, 4}
len1: 3  len2: 4
In[7]:=

2)
In this example, len1 and len2 are not assigned values, because status1 is
assigned to status directly.
In[2]=status = {len1, len2}
status1 = {3, 4};
status = status1;
Print["status: ", status];
Print["len1: ", len1, "  len2: ", len2]

Out[2]= {len1, len2}
status: {3, 4}
len1: len1  len2: len2
In[7]:=

My question is:
Can the result of example 1) be achieved in any way using the variables
status and status1
