[PD] passing symbols into an abstraction

[jfm3]

I have two patches.  stereo-sample.pd reads the given file name into 
tables, and at the outlets puts the size of the sample, the name of the 
left table, and the name of the right table.  foo.pd tests 
stereo-sample.pd.  I can't figure out how to get these to work, and Pd33 
crashes when I click on the message connected to the inlet to 
stereo-sample.pd.  Thanks in advance for any help.
