How to handle a NULL value with Packed Decimal (COBOL Copy book).
I get below error when i try to parse a record when NULL occurs for a PD,
10 BNK1-MEET-YR PIC 999 COMP-3.
ConversionException BIP5505E: A data conversion failed because the data was invalid.
Type of data being read: 'packed decimal, no sign found '
Data: '0x0000'

Thanks for your help

Hi Rajeev,

If you are seeing a X'00' data then it is a NULL. Null values cannot be passed to PIC S9(X) COMP(3) fields or the Broker will not be able to parse it as a packed decimal field. They must be explicitly set to zeroes [MOVED ZEROES] and not LOW/MIN values [As they are known in Mainframe lingo].
The mainframe application will by default retro fit a sign and then send it across to your application.
Thus you should be receiving a X'C00' for the packed fields in question.

Hope that Helps,

kimbert

rajeevreddy: Please don't double post. This thread looks almost identical to http://www.mqseries.net/phpBB2/viewtopic.php?t=46970
harish_td: Message broker is smarter than you think. Take a look at the other thread.
