Thanks a lot, John. I didn't know that. Maybe that info could be added to the manual?
All the best, 
Andreas

    We have seen this before.  If _ is a valid characteristics a name then $V_ is an undefined macro.  You need to use $V._ to get concatenation.

$NAME

$NAME — Calls a defined macro.
Description

Macros are textual replacements which are made in the orchestra as it is 
being read. The macro system in Csound is a very simple one, and uses the 
characters # and $ to define and call macros. This can save typing, and 
can lead to a coherent structure and consistent style. This is similar to, 
but independent of, the macro system in the score language.

$NAME -- calls a defined macro. To use a macro, the name is used following 
a $ character. The name is terminated by the first character which is 
neither a letter nor a number. If it is necessary for the name not to 
terminate with a space, a period, which will be ignored, can be used to 
terminate the name. The string, $NAME., is replaced by the replacement 
text from the definition. The replacement text can also include macro 
calls.

Many thanks for the help. I didn't think of checking the $NAME entry.
Best, 
Andreas
