Define Code Block Option makes a lot of sense.

Now fer a simple quiz. What does EBCDIC mean?

That's easy. Google it.

Ah, but without Google, what does it all mean? Extended? Binary Coded Decimal? The IC is more or less obvious.

Extended = an alphanumeric character set that is more inclusive (extended) than the original BCD set. Presented as a 7 digit binary code.

BCD = decimal numbers expressed in four digit binary format.

Binary coded decimal. Yes 4 bits. 0₁₀ = 0000₂ 1₁₀ = 0001₂ 2₁₀ = 0010₂ . . . 9₁₀ = 1001₂ That is as far as it goes.

Hexadecimal goes a little further

A₁₆ = 1010₂ F₁₆ = 1111₂ still 4 bits. However hex is usually expressed as two nibbles(8 bits). Thus 1A in hex = 00011010₂

I was always amazed at folks who insisted that "hex" was something 'different' from binary. Hex is merely a short hand alpha-numeric representation of binary. Sure made things easier!(until Intel came up with high/low nibble swap)!:rolleyes:

Y'all may find this boring, but I believe Bill will understand!!!;)

There are 10 kinds of people in the world: those that understand binary and those that don't.

Then there are the other 8 kinds!:D

No, 10 covers both types of people.

Not in binary!

[quote="BuckeyeDennis"]Not in binary! ]

Octal IS binary grouped in 3 bits.
