PACKED DECIMAL reserves half byte per character. To store in packed decimal use COMP-3.
The internal format of storage is 8421.
Zoned decimal reserves one 2B/ 4B / 8B depending on the no of inputs.
Use COMP / BINARY to store in Zoned Decimal.
The internal format is Binary. |

Hi Pryia,
What you describe as Zoned Decimal is really Binary. Zoned Decimal is External Decimal (usage DISPLAY).
A Zoned Decimal number is represented in storage as e.g. F1F2F3C4 for a positive 1234. The Fs and the C are the zones. |
