{
#define pFILENAME ((char FAR *) _HandToPtr(parm->p[0].val.ev_handle))

   if (!_SetHandSize(parm->p[0].val.ev_handle,
      parm->p[0].val.ev_length+1))
   {
      _Error(182); // "Insufficient memory"
   }
   pFILENAME[parm->p[0].val.ev_length] = '\0';

   _HLock(parm->p[0].val.ev_handle);
   wh = _EdOpenFile(pFILENAME, FO_READWRITE);
   _HUnLock(parm->p[0].val.ev_handle);

   _EdSelect(wh, 0, 1);
   _EdCopy(wh);
   _EdSetPos(wh, 2);
