If you like to use numeric . instead of normql , to separate decimals in 
spreadheets:

You can hexadecimal-edit a copy of /WINDOWS/SYSTEM/KEYBOARD.DRV (it is 
protected for running windows). 

Search and replace de string "*-+." (without ") and change [.] by [,] (without 
[], two times in the spanish keyboard)

Reboot in Ms2: backup the original KEYBOARD.DRV and copy the new KEYBOARD.DRV 
in your /WINDOWS/SYSTEM directory.

After reboot, you can press de number keypad [.] and you will see [,] in 
NOTEPAD and windows applications; you will see [.] in msdos console.

Spreadsheets run fast with decimal comma in [.] number keypad!
