A method of producing an executable image from an object file without shared library support from the operating system, wherein the executable image requires a shared library file in order to resolve at least one of the symbols called for in the object file. A method of optimizing the loading of a previously linked file into working memory in a computer for executing in a single address space of the working memory, the file containing an instruction to make an indirect jump to a location in a shared library through an import section of the file. A method for optimizing the loading of a previously linked file into working memory in a computer for executing in a single address space of the working memory, the file containing plural sections with number-filled padding between the end of each section and a succeeding page boundary. A method of optimizing the loading of a previously linked file into working memory in a computer for executing in a memory sharable with other executables. This method includes selecting a portion of code in the previously linked file, removing the portion of code from the previously linked file, and constructing a dynamically linked library file containing the portion of the code, the dynamically linked library file being available to plural files including the previously linked-file. A method of converting an image which has been previously linked for executing in an unshared memory into an image optimized for use with virtual memory.
