I am having some problems in OS X with RUN filename$,refNum%. It 
basically does nothing. I want to use this to open a PDF file of 
instructions directly from my program. My reference number is obtained 
from a user previously opening a required file in a folder with 
FILES$(_fOpen,. Upon testing it appears that  the returned value of 
refNumVar% does not vary with the folder location of the file selected 
which probably means that my RUN statement cannot find the file with 
the specified name.

Can someone tell me if RUN filename$,refNum% does work in carbon before 
I spend lots of time trying to find the problem?

Does anyone know of carbon examples in the examples/donations files for 
RUN?

Thanks
