[ACT-R-users] Question regarding buffer-chunk command via RPC

[Dan Bothell]

That is the correct return value from buffer-chunk when given a buffer 
name.  It returns a list of the names of the chunks in the buffers 
provided, and that is all that is returned in Lisp as well -- the (D-0) 
at the end.  The output to the command-trace with the buffer's chunk 
information is a side effect of calling buffer-chunk, and you will see 
that when you call it remotely as well.

If you want the text output that is shown, you can use the 
printed-buffer-chunk command.  If you want to know what slots a chunk 
has, then you would use the chunk-filled-slots-list command, and to get 
the value of a slot in the chunk you would use the chunk-slot-value 
command.
