This post is more for completeness and so hopefully help someone someday.
i now have my code working as i want it to so am posting it here.
and as you can see i have had to rework it from my original post.
please note ...
that I have had to use a case statement inside the keypress do block.
created a define block for the if tests and the actual test has changed
to
check on the length of the text as apposed to nil or false as before.
would've liked to have the :enter & "\n" in 1 when clause to have saved
the
define but i couldn't figure it out (after using some like values -
semi-comma
& comma, space).
hope this helps someone in future,
Dave.

para strong 'customer name'
@custname = edit_line :width => 270
keypress do |key|
case key

when "\n"

end
end
end

para strong 'data return shown here!'
end
