Whoa! I would have never found that out by myself. :) Thanks Urs & Jan-Peter. I have to check the Scheme link, too.

Hi Risto,

you might go this way:

lineThickness = 5
\markup \override #`(thickness . ,lineThickness) \draw-hline

That is semi-quote the pair with ` (instead of ') and then "unquote" the
variable to retrieve the value with a comma (,)
