I recommend reading about multiple assignment in NuVoc.
http://www.jsoftware.com/jwiki/Vocabulary/Assignment
Multiple assignment can assign different values, as Raul points out. It
also removes one level of boxing:
'a b' =: <5
a
5
b
5
a =: b =: <5
a
+-+
|5|
+-+
b
+-+
|5|
+-+

A Quick Question:
Is there any difference between:
' var1 var2' =: 10
and
var1 =: var2 =: 10
?
JforC breifly mentions the handy multiple assignment (the former, above)
http://www.jsoftware.com/help/jforc/more_verbs_for_boxes.htm
but doesn't mention the two are equivalent. From my brief experimenting it
seems they are. I'm guessing for a long list of variables the former is neater.
