       |                    \[t l ]
       |
       |
       |      [13 5 (                              <-- set values for output here;
       |       |                                           this means index 13 from the fifth "list"
    __|___[t b l ]
   /   |             |
  /   |             [unpack ]
[list ]             |          |
 |                   |   ___[* 20]                <-- list number * "list" length
 |                  [+ ]                             <-- and add to the index
 |                   |
 |__________[set, adddollar $1 (
