Thanks, Nick.
I'll fiddle with it some and see how it works for me.

Subject: spanner question
Hello folks,
I have a question about a text spanner in a pre-defined variable.
In the snippet below, the first example does everything I want except
that in the first line of music, the spanner line doesn't extend to the
barline at the end of the line. I've achieved this by using two
pre-defined variables for the text spanner I want: one to start it, and
one to finish it with a terminal ending.
In the second example, the spanner extends to the end of the first line
of music (with a terminal ending that I *don't* want) and then, starts
too far to the left on the second line. The terminal ending at the
conclusion of the chord acts the way I want it to.
My goal is to define a single variable (perhaps a music function) that
will fulfill these requirements:
* Extends over multiple systems, extending to the last measure's
barline without the terminal ending
* Picks up at the beginning of subsequent lines with identical
positioning as the initiation of the spanner
* Dynamically adds a terminal ending to the end of the spanner
Has anyone worked on this issue already (possibly with a scheme
function)?
Also, the final destination for this is most probably going to be a
"\include" file with many (dozens?) pre-defined variables for common
text spanners used in guitar music. If I achieve the results I hope
for,
I plan to share it with the community.
Thanks,
David
