Sudoku Puzzle Game

These are the files you need. You can send them from the package contents below.

• SUDOKU.EXE → A:\SOFT programa de DOS 5.1 KB
• SUDOKU.ICN → A:\SOFT icono, junto a su aplicación 200 B
• SUDOKU.DAT → A:\_DAT configuración 14.6 KB

No need to put Sudoku.txt: they are manuals, source code or supporting material. Read them here and save 1.7 KB on a 1 MB disk.

1. Copy SUDOKU.EXE to A:\SOFT. They are DOS programs: run them from the DOS icon, or add A:\SOFT to the PATH in C:\AUTOEXEC.BAT to call them by name.
2. Copy SUDOKU.DAT to A:\_DAT, where the 200LX looks for configuration. Open it with Memo and adjust it before use.
3. If you edit a configuration file on the palmtop, make sure you leave a newline at the end: some programs swallow the last line without saying a word.
4. The .ICN files are icons: they go in the same folder as their application.

Derived from the package contents and the 200LX conventions. It installs to A: on purpose: C: is a RAM disk and every byte there is memory taken from the system.
