Thanks again Romano,

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.)
