Here's a variation that favors readability over esoterica. This
way you can use whatever names you like, and do other things with
them than just print the (sub-)block of values.
>> rowlength: 5
== 5
>> s: data
== [1 AAA BBB 3 0
2 MMM XXX 1 1
3 DDD VVV 2 1]
>> forskip s rowlength [
[ use [u v x y z] [
[ set [u v x y z] copy/part s rowlength
[ print [v x y z y + z "(" u ")"]
[ ]
[ ]
AAA BBB 3 0 3 ( 1 )
MMM XXX 1 1 2 ( 2 )
DDD VVV 2 1 3 ( 3 )
As far as BIND itself, please see my note to Chris about how that
one works. That might explain why "a" through "e" are the only
names which work at the end of the BIND phrase.
HTH!
