Details

In packed decimal format, each byte represents two decimal digits. An IBM packed decimal number consists of a sign and up to 31 digits, thus giving a range from 10³¹ -1 to 10^-31 +1. The sign is written in the rightmost nibble, with a 'C'x indicating a positive value and a 'D'x indicating a negative value. The rest of the nibbles to the left of the sign nibble represent decimal digits. The hexadecimal values of these digit nibbles correspond to decimal values; therefore, only values between '0'x and '9'x can be used in the digit positions. The following table shows several examples of how data is read using the PDw.d informat.
