integers?
For 1 to N, yes (based on jn's code:
Iota: function [N [integer!]] [Block] [
Block: make block! N
repeat I N [insert tail Block I]
Block
]
>> iota 6
== [1 2 3 4 5 6]
If you want to put in a refinement /Initial etc, feel free.

That's correct. Check out Rebol Core .pdf manual, page 261, 8-19, Local
Variables Containing Series for an explanation.
Alternatively, use:
testblock: copy []
or:
testblock: make block! YourLengthValue
