Victor,

Attempting to implement your pointer, I tried the following:

1) I added the line:
self.ready = True
before my call to set_filechannel

2) In the set_filechannel method (in csndsugui), I commented out lines 3, 5 
and 6 - leaving only the call to csound.SetChannel.

Neither of these changes made any difference; still no filename, nor even 
"ahha" passed to my csd.

Please note that I also tried a sequence that first selects and compiles the 
csd, whereupon the performer selects a variety of performance parameters 
passed successfully via chnexport *and selecting the desired file from the 
Journal (our issue)*, then performing. Passing all the other values works 
fine (of course, different methods are employed). Same result.

Any further suggestions are most welcome (from anyone).

Victor, I really appreciate your help trying to troubleshoot me through 
this.

You should not add self.ready = True, because this is a test of  
compilation, which should
not be done by you, only internally. In any case, the test was for it  
to be False, not True. If
Csound has not been compiled, the SetChannel() call will not do  
anything, so none of the
things you've done will correctly test this.

Did you try writing a simple application based on the csndsugui  
examples in the git repository,
like the Playfile activity?

I would suggest you do so. My idea for csndsugui is that some methods,  
like set_filechannel()
do not necessarily need to be called directly. If you use a  
filechooser like this:

win.csd("playfile.csd")
win.filechooser(bbox,"soundfile")

you will get a filechooser button which will open a dialog and the  
selected file will be
passed to the CSD in the "soundfile" channe, like so:

S1 chnget "soundfile"
i1 strcmp S1,"0"
  if i1 != 0 goto continue
  puts "no filename selected !!", 1
  turnoff
  goto end
  continue:
...

If you are not using this mechanism, then you may as well call the  
Csound class method
SetChannel() directly, or via the set_channel() wrapper (which checks  
if self.ready is not True).

directly:
obj.csound.SetChannel(name, string)

via set_channel
obj.set_channel(name, string)

where obj is your CsoundGUI object.

If csound is compiled, any of these will work. They will fail if  
csound is not compiled.
