Abstract: A method for use in an electronic digital signal processing system for improving execution time in locating requested programs, reducing program storage requirements in memory and improving packaging and repackaging of programs on direct access memory devices for the library. A program data set for a system is formed to recognize the references to character program names and to resolve those references into control section identification codes. Each referenced character program name is uniquely encoded to a 16 bit control section identification code used as an input to a table lookup routine. The encoded control section identification for the program library loaded on the direct access memory consists of a data set number, a module index number and a control section number. A similar data structure is used to locate programs in storage by program management once they have been retrieved from the program library stored on a direct access memory device of the system.
