I'm wondering if you need to name the checkboxes. The example below shows a
way of using some code to traverse the generated layout to set the
checkboxes. Also, an interesting program to read is rebodex.r in the Rebol
script library.

; Lets generate a layout of 10 checkboxes.
; When the button is pressed a function runs
; through the layout searching for check boxes.
; It sets the every other check box it finds.
;
; I wrap all the code in a context just to tidy things up,
; you can run the code without using a context too.
;
checkbox-example: context [
layout-script: copy [
title "A checkbox manipulation example"
button "Set checks" [set-odd-boxes] across
]
for i 1 15 1 [
append layout-script [check]
]
lay: layout layout-script
set-odd-boxes: does [
check-count: 0
for i 1 length? lay/pane 1 [
fce: lay/pane/:i
if equal? fce/style 'check [
check-count: check-count + 1
if equal? 0 (and check-count 1) [
fce/data: true
]
]
]
show lay ; Update the display
]
go: does [
; See the result
view lay
