Hi,
I have a requirement where I need to create a header and a trailer record for a mainframe application.
The header record starts with Hex(00) and trailer starts with hex(FF).
I tried the below code:
SET rHead.StartField = CAST(x'00' AS CHAR CCSID OutputRoot.Properties.CodedCharSetId);
And
SET rTrail.StartField = CAST(x'FF' AS CHAR CCSID OutputRoot.Properties.CodedCharSetId);
OutputRoot.Properties.CodedCharSetId is coming out to be 1208.
The output is being validated using a DFDL parser where this field is defined as a String with length 1 and length units as bytes.
The first statement is working fine, but while setting x'FF' it throws an error as below:
ImbConverterCPP::internalToUnicode
BIPmsgs 3 2135
Unconvertable character
Type 5
Text FF
Type 2
Text 1208
Please help. |

That's to be expected: FF as a hex value is not associated with any character in CCSID 1208.

| so what could be a possible solution to it? Mainframe app still wants x'FF' as the first character in the trailer record |

Thanks for the link, I am reading it now. I am a bit newbie in this area though.
Other IIB integration with Cobol app uses 1208 CCSID, so I thought of using the same.
Other interfaces don't need to use x'FF' so they work fine, my interface needs it so failed. |

You just got lucky. You should always pay attention to the CCSID when working with character data. You have just found out why

Technically, the other interfaces need it too. They just haven't failed yet. If you work in this business you need to be just a little bit paraniod! |
