Hi,
I know that if the sign bit stored is
C - if it is a signed positive
D - if it is a signed negative
F - if it is unsigned
But any one tell me what is G in sign bit represent?
Thanks & Regards

from Your premises assuming that You are talking about the four bits
which represent the sign....
Your question is weird, or worth patenting a new bit architecture/convention
if on the other side You have a packed number containing a positive 6 x'7c'
when You unpack it You get a x'c7' that when printed shows up as c'G"
but the question as You posed it does not make much sense  |

The sign 'nibble' is only four bits long, the only values that fit are the hex digits from 0 to F, G is not a hex digit....... |

| BTW, CICS Guy and others, why isn't this called a "nybble"? |

wikipedia treats them in the same way
| Quote: |
| A nibble (often, nybble) is the computing term for a four-bit aggregation, or half an octet (an octet being an 8-bit byte). As a nibble contains 4 bits, there are sixteen possible values, so a nibble corresponds to a single hexadecimal digit (thus, it is often referred to as a "hex digit" or "hexit"). |
