In summary, to access the extended ASCII character set in DOS, hold down the <Alt> key while typing the decimal number on the keyboard keypad. In Windows, you can also use the <Alt> key to type the decimal number for a DOS character or hold down <Alt> and type "0" followed by the decimal number for a WIN character. On a MAC, use keystroke abbreviations such as <op> and <sh> to access extended ASCII characters. Alternatively, you can use the character map under start->accessories or copy and paste from online sources.

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

Extended ASCII set on MAC

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

Keystroke Abbreviations:
<op> Option key
<sh> Shift key
<sp> Space bar

Keystroke Examples:
<op><sh>a Hold down the Option, Shift and "a" keys simultaneously, then release the keys.
<op>c Hold down the Option and "c" keys simultaneously, then release.
<op>e E Hold down the Option and "e" keys simultaneously, release, then type a capital "E".

What is the Extended ASCII character set?

The Extended ASCII character set, also known as the Extended ASCII code, is an 8-bit character encoding system that can represent up to 256 characters. It is an extension of the standard ASCII character set, which only includes 128 characters.

How do I access the Extended ASCII character set?

In order to access the Extended ASCII character set, you can use a computer program or application that supports this encoding system. You can also use a special keyboard that has the extended characters printed on it.

What are some common uses for the Extended ASCII character set?

The Extended ASCII character set is commonly used in computer programming and data communication. It is also used in various languages and special characters such as symbols, mathematical symbols, and diacritical marks.

Can I use the Extended ASCII character set on all computers?

The Extended ASCII character set is widely used and supported on most computers, but there may be some older systems or devices that do not support it. It is always best to check the compatibility of a device or program before attempting to use the Extended ASCII character set.

Are there any limitations to using the Extended ASCII character set?

One limitation of the Extended ASCII character set is that it is not a universal standard, meaning that different devices or programs may use different versions of the character set. This can cause compatibility issues when trying to transfer or display text using the Extended ASCII code.
