The purpose of HP41_ProgEnv.XLS spreadsheet and its associated macros and tool bar is to provide a kind of HP-41 programming environment.

- export and import function to save the program as Text file (for their later compilation);
- compile and de-compile function (with prior/post export/import) using Leo Duran's HP41UC.EXE program;
- launch the HP-41 emulator on successful compile and load the new code (V41.exe program);
