hii,
packed decimal internal format is hexadecimal,here one seperate nible is occupied for sign ,but in zoned decimal case no seperate nible for sign,sign will zoned on last byte only.

In zoned decimal format sign will be over punched on the data byte (lastbyte).
In packed decimal format sign will take 1/2 byte extra to store separately.
