bilingual data excluidng code switching

[Yahya E-rramdani]

Dear,
I am working a bilingual data Berber-Dutch, when analysing VOCD, I 
want to exclude trings coded as [$nl] when the target language is 
Berber. How shall I do that in CLAN?
N.B. for singel words, the following command is used:  -s*@nl.

Thanks in advance.

Yours,
