Abstract
A data processing system executes a spreadsheet program that supports callbacks from dynamic-link libraries. The dynamic-link libraries may callback into the spreadsheet program through an entry point provided in the spreadsheet program. These callbacks allow execution of spreadsheet program functions and commands from within the dynamic-link library. The ability to callback to the spreadsheet program from the dynamic-link library results in substantial savings in time and memory space.
