This for example:

The thing is that in a narrow sense, in Logo, "lists" are the things
that you see between brackets in code, for example:

tto [t1 t2 t3 t4 t5]

or the "instruction list" that "repeat" receives:

repeat 4 [fd 100 rt 90]


But then MicroWorlds incorporated "Text Boxes" and they do also behave
a lot like lists:

* you can store data in them
* they have items
* they can be empty
* you can change they content
* you can pick items from them


I guess that, people who are familiar with MicroWorlds more that with
other tools, see the distinction between lists proper and textboxes as
artificial...
