Opening a Stream file in the root directory

I am trying to open a stream file in the root directory of the HFS.
Each time I try it I get the error CPF1F83 (File System name xxx not found).
I've also tried subdirectories and get the same error.
If I try to open it within the QDLS file system, everything works fine.  But
I don't want to do this!

Here's a snippet of the code:

 D #pPathInLn      s              9b 0   
 D #pAttribLn      s              9b 0   
 
 C     ' '           Checkr    PathIn        #pPathInLn               
 C                   Call      'QHFOPNSF'                             
 C                   Parm                    #pHandleIn       16      
 C                   Parm                    PAthIn                   
 C                   Parm                    #pPathInLn               
 C                   Parm      '100 100   '  #pOpenInf        10      
 C                   Parm                    #pAttribIn        1      
 C                   Parm      *Zero         #pAttribLn               
 C                   Parm                    #pAction          1      
 C                   Parm                    DSErr                    
 C     ErByta        IfNe      *Zero                                  
 C                   Move      ERMsid        PMsId                    
 C                   Movel     ErMsDt        PMsDt                    
 C                   Exsr      Close                                  
 C                   Move      '1'           *inlr                    
 C                   Return                                           
 C                   EndIf                                            

PathIn is passed to the program and is 50 bytes long.

Any ideas?
