Like standard format,
zoned decimal digits are represented as EBCDIC characters. Each digit
requires one byte. The rightmost byte represents both the least significant
digit and the sign of the number. Digits to the left of the least
significant digit are written as the EBCDIC characters 0 through 9.
The character that is written for the least significant digit depends
on the sign of the number. Negative numbers are represented as the
EBCDIC printable hexadecimal characters D0 through D9 in the least
significant digit position, and positive numbers are represented as
hexadecimal C0 through C9. If the format includes a
d value,
the number is multiplied by 10
d.
If an overflow occurs,
the value that is written is the largest value that fits into the
output field; the value will be positive, negative, or unsigned, as
appropriate.
The following table
contains examples that illustrate the use of the zoned decimal format:

Note: In these examples, the Value
column represents the value of the data, and the Results column shows
a hexadecimal representation of the bit pattern that is written by
the corresponding format. (You cannot view this data in a text editor
unless you view it in hexadecimal representation.) For a table of
commonly used EBCDIC characters, see
