I appreciate the effort you and all the others have taken to show me the
error of my ways.
I've reworked your code to fit my "real world" -- both
Boxcolor and Lastfield musy be strings -- they are sourced
from a spreadsheet. And it works with Compose.
I dunno, this sort of thing is a matter of taste as much as
anything, but I reckon the original "makelayout" is an easier
bit of code to follow and amend than the version below. The
compose
version needs several Rebol tricks (to-set-word,
get to-word) that the (perhaps brain-dead and inelegant)
string 'em up
original doesn't.
(And I guess when I write code, the target audience I have in
mind includes the maintenance programmer in 5 years time who
is not an expert in either the system or the languages used
but, nonetheless has to make modifications fast.)
Thanks all again,
Colin
