I know the following code works.... The only difference is that you allocated
1 space for an OStype, where SFTypeList allocates 4.  Hmmph.

{  SFReply reply;
  SFTypeList typeList;
  Point Pt;
  
  Pt.h=100;
  Pt.v=100;
  
  pStrCopy(FileName,"\p");
  SFGetFile(Pt,"\p",0L,-1,typeList,0L,&reply);
  if (reply.good)
     pStrCopy(FileName,reply.fName);
      
  *vref=reply.vRefNum;
  
  return reply.good;
}

It sorta looks like the same piece of code, huh?
