In what way does this not work for you?

The use of variables in cc files should work fine, as long as you don't 
accidentally name the variable the same as a variable in 
combinations.pl, in which case you may or may not get undefined 
behavior. Your variable name seems fine in that respect.

Also, as Saikumar indicated, specifying basedir in the cc file may cause 
some problems under certain circumstances. Especially if you are using 
two servers (basedirs) in one RQG command, or mixing single-server and 
dual-server commands in the same cc file. But it does not seem like that 
is what you are trying to do.
