Like numbers stored in standard format, zoned decimal
digits are represented as EBCDIC characters. Each digit requires one byte
of storage space. 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 represented as the EBCDIC characters 0 through 9. The character
printed for the least significant digit depends on the sign of the number.
In the least significant byte, negative numbers are
coded with the high-order nibble being a 'D'x and with the low-order nibble
being the numeric value. Positive numbers are represented with the high-order
nibble being a 'C'x. For example, compare the zoned decimal data for 123 and
-123 in the following table.
