For those who are interested in accessing extended ASCII character set.

In DOS:
Hold down the <Alt> key while typing the decimal number on the keyboard keypad. (Example: <Alt>178)

In Windows for a DOS character:
Hold down <Alt> while typing the decimal on the keyboard keypad. (Example: <Alt>230)

In Windows for a WIN character:
Hold down <Alt> while typing "0" then the decimal number on the keyboard keypad. (Example: <Alt>0140)

To get ñ

1) activate Num Lock

2) hold down Alt key

3) on number key-pad (usually below Num Lock), type 0241 (while holding down Alt key) and

4) then release Alt key.

so "Alt+0241" gets ñ
