Patent ID: 7519951

Claim:
A method of creating a dynamically linked computer program function package, the method comprising: establishing an attribute, each attribute exhibiting a plurality of at least one of variations, characteristics and parameters associated with a specific computer program function; obtaining a source file associated with said specific computer program function; compiling said source file iteratively to create a plurality of corresponding object files based on said at least one of variations, characteristics, and parameters for each said attribute, wherein each iteration of the compiling said source file results in the plurality of object files having the specific computer program function but with each object file having distinct attributes from one another; and linking the plurality of resulting object files to create a single executable file, such that the single executable file comprises different versions of the specific computer program function; and wherein said single executable file is configured to facilitate choice of a selected version of said specific computer function based on a particular said at least one of variations, characteristics, and parameters for each said attribute; and wherein said attribute includes: version, addressability, character code base, character set that a specific operating system supports, system linkage conventions; machine architecture, or floating point hardware; and wherein said at least one of variations, characteristics, and parameters for each said attribute includes, 64-bit versus 32-bit addressing; ASCII versus EBCDIC, internal representation for character data, or HEX versus IEEE representation to use for floating point data.
