thanks for your fast replies. David’s suggestion does just very fine.
But this begs the question why you don't just assign the whole tempo
specification to a single variable.
Of course, you are right! But I was using this request as an example for some other questions I had (And they are also answered now!!). The point is, that I have built a template, that makes it possible to print several editions of the same piece. For that I sometimes need the possibiliy to exchange the wording of the tempo into different languages "automatically".
