shim
     
         A small piece of data inserted in order to
        achieve a desired {memory alignment} or other addressing
        property.  For example, the {PDP-11} {Unix} {linker}, in split
        I&D (instructions and data) mode, inserts a two-{byte} shim at
        location 0 in data space so that no data object will have an
        address of 0 (and be confused with the {C} null pointer).
     
        See also {loose bytes}.
