Saq,
Thanks, I did understand your point, and expected <local-value> to be empty
and could not make it so, Although '<<local-value>>' always returned ''
when empty.
But as I read in the following example it appears to be blank? thus if !is[
blank] no value will be returned and else is engaged.
*Perhaps we can say an empty run is blank not empty?*
Thus as you suggested !is[blank] changes blank to empty.
Thus in the case of [<varname>] an empty varname returns blank not empty.
I have decided to take another path, dynamically create a macro eg "\define
setting() value"
This reply was Posted now, I forgot to post it yesterday.
Thanks for you help
Tones
