[Jprogramming] Sets please help

[km]

I get

   set  NB. Argument y should be a box or list of boxes
[: /:~ ~.
   set 0;1
+-+-+
|0|1|
+-+-+
   set <0
+-+
|0|
+-+
   set <''  NB. no space between quotes
++
||
++
   set <' '  NB. space between quotes
+-+
| |
+-+

Also

   '' -: set ''  NB. No space between quotes in either pair of them
1

Here the argument to verb set is an empty list which I can regard as a list of boxes.
