I was looking over some code in my program and all of a sudden I got
nervous. The following bit of code works, but should I be locking resHand&
before copying data from it? 

resHand&=FN GETRESOURCE(_"GeoJ",id)
  err% = SYSERROR
  siz&	=	FN GETHANDLESIZE(resHand&)
  LONG IF resHand& <>0 and err%=_false                              'NOT err%
    CALL SETRESLOAD(_True)
    CALL LOADRESOURCE(resHand&)
    adr&=PEEK LONG (resHand&)
    recAdr&=@gGrad
    BLOCKMOVE adr&, recAdr&, _bSz
   END IF
  CALL RELEASERESOURCE(resHand&)
