ocation quantum. In current version of DyBASE size of
allocation quantum is 64 byte. It means that size of all allocated objects is
aligned on 64 byte boundary. Each 64 byte of database memory is represented by
one bit in the bitmap. To locate hole of requested size in bitmap, DyBASE
sequentially searches bitmap pages for correspondent number of successive
cleared bits. DyBASE use three arrays indexed by bitmap byte, which
makes possible fast calculation of hole offset and size within the byte.<P>
