TNS object files can be processed by the Accelerator or by the TNS Object Code Accelerator (OCA) to produce to produce accelerated object files.
TNS to native-mode access shell A shell object file, generated by the shell generator, that supports procedure calls from TNS object files to a particular TNS/R native-mode or TNS/E native-mode library routine. The shell suspends TNS code emulation, copies and reformats parameters from the TNS execution stack to the native execution stack, calls the desired routine in native mode, copies back the function result, and resumes TNS code emulation.
