Abstract: A compiler extension for the compile-time verification of programmer-defined data dependencies. The compiler extension provides for a check statement which takes as an argument a data-verification expression. The data-verification expression has a predetermined value when the programmer-defined data dependency is conformed to in the program. A compile - time error is generated if the data-verification expression does not have the predetermine d value on the compilation of the check statement. The successful compilation of the check statement does not result in run-time code or run-time data allocation occurring.

Abstract: A method for managing storage for allocation and de-allocation requests of fixed size data objects. Fixed size data objects are allocated and de-allocated from a page list comprising a pool of memory pages and each page includes a reserved area for storing object information in common to all the objects in that page. A pool of pages, i.e. page list, is provided for each specific object size. A recycle page list is also provided for recycling pages in which all the objects have been returned.
