1. A non-transitory computer storage medium having computer readable instructions stored thereon that, when executed by a computer, implement a method creating a dynamically linked computer program function package, the method comprising: establishing attributes, 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 the specific computer program function; compiling the source file iteratively to create a plurality of corresponding object files based on the at least one of variations, characteristics, and parameters for each attribute, wherein each iteration of the compiling of the source file results in the plurality of corresponding object files having the specific computer program function but with each corresponding object file having distinct attributes from one another; and linking the plurality of corresponding object files to create a single executable file, such that the single executable file comprises different versions of the specific computer program function; wherein the single executable file is configured to facilitate choice of a selected version of the specific computer program function based on a particular of the at least one of variations, characteristics, and parameters for each attribute; wherein the attributes include: version, addressability, character code base, character set that a specific operating system supports, system linkage conventions, machine architecture, or floating point hardware; and wherein the at least one of variations, characteristics, and parameters for each 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.
