Re: Array variables and loops (for lyrics)

[Mauro Levra]

Wonderful! Thank you very much. It works perfectly.

Is is possible to conditionally execute the #@ expression based on 
whether the 'textArray' variable is bound?
I have tried, but I have not succeeded. As a workaround I have defined 
an empty 'textArray' in my head.ly which is sometimes redefined by 
my-score.ly
