Hi Brett!
You said "Yell", well I´m yelling!
"result-block: make block! (multiply 2 length? index-block)!
could you tell me why you initialized the block in this form? I´ve noticed
that you pass references to blocks and words by copying, e.g
newblock: copy []
does it have an advantage over
newblock: make block! 0 ?

foreach [char file-list] index-some-data read %. [
write-my-page char file-list
]
I presume you "read" the directory in "index-some-data" but without the
colon? I expected something like this
foreach [char file-list] index-some-data: read %. [
write-my-page char file-list
]
-----------------------------------------------------------------------------------------------------------------------------------------------
That means I just have to parse the <title> tag contents of all the files
in a given directory and pass it as "some-pagerefs" items ?
generate-my-page: function [
page-number
some-pagerefs [block!]
][html-page][
html-page: copy {}
append html-page reduce [<h1> "This is page " page-number </h1>]
foreach pageref some-pagerefs [
append html-page <p>
append html-page build-tag reduce ['a 'href pageref]
append html-page pageref
append html-page [</a> </p>]

This is one of the parts that I like best
"either indexed-item: find index-block first item ["
I never thought that the left to right evaluation in REBOL could also be
passed as a expression to "either" or "for"
Thanks Brett for your help
Best regards
