Testing this a bit on my computer - the environment "variable" $PWD is 
the local directory.  When using this in AIPS. it is the directory 
(folder) that you were in when you started AIPS, not the 
folder/directory in which the window now finds itself.  My previous 
suggested test will not be helpful.  Exit AIPS and make sure that the 
window has been cd'd to the directory containing your data files.  Then 
start AIPS up again.
