One possible source of error is that the toolbox expects a Pascal string.  
your declaration should read :
   char fname[255]  = "\pdezaley:user:journal4.dat";

  Also, I've encountered cases where MPW dosen't like references to char 
arrays of the form Somecall(fname) where fname is declared as above.  Even 
though it's kinda' ugly,  Somecall (&fname[0]) seems safer. 
  If you're going to be creating files that stick around it's generally 
better to use a SFPutFile, rather than hard-wiring it into your code.  
Another alternative is to put your journal files into the blessed folder -
