[REBOL] A surprise from REPEAT
From: larry:ecotope at: 1-Aug-2001 19:56
Hi all,
I just got a surprise from the REPEAT function. We all use it in the
standard form of
>> blk: [x y z]
== [x y z]
>> repeat j length? blk [print j]
1
2
3
where the second argument to REPEAT is the number of repetitions, and j
iterates from 1 to that number. Well I inadvertently left LENGTH? out of my
statement and got this instead
>> repeat j blk [print j]
x
y
z
So REPEAT has the same capability as FOREACH to access each item of a
series.
I don't recall seeing this documented anywhere, so I thought I would mention
it here. It sure surprised me!!
