  • Object code processing system for forming an executable image by tranforming LISP-type object files into a format compatible for storage by a linker
    Patent number: 5303380
    Abstract: A system for processing code contained in one or more selected files, before the code is linked to form an executable image, determines the locations in memory where the code will be stored after it is linked, and revises the code to correspond to the determined memory locations. The object code files include code comprising a programming environment, such as LISP, and code input by a user. The user can delete selected portions of the programming environment. Read only, static, and dynamic memory are utilized and each portion of the code input by the user is evaluated to determine which memory is most appropriate.
