In both sign is stored at last byte but
In PACKED Decimal is at last nibble where as in ZONED decimal sign is stored at higher nibble of last byte
Eg.
+1234 in zoned decimal it will be stored as F1 F2 F3 C4
-1234 in zoned decimal it will be stored as F1 F2 F3 D4
+1234 in PACKED decimal it will be stored as 01 23 4C
-1234 in PACKED decimal it will be stored as 01 23 4D
