Sign Nibbles in Zoned and Packed Decimal Items

Items that are zoned, such as PIC S999 or packed decimal, such as USAGE PACKED-DECIMAL or COMP-3, contain a sign nibble which is half a byte.

There is a small difference in processing the items mentioned previously in zOS system and IBM i system. On zOS system, positive values in signed items such as PIC S999 contain nibble xC, while on IBM i system, such items contain nibble xF.

During parsing, the plug-in recognizes both variations. However, during rendering, you have to specify what flavor of behavior is needed. You can use the IBM i Sign Nibbles check box of the Render activity. Select this check box to generate IBM i flavor. Clear the check box to generate zOS flavor.
