Migration to the COBOL Reader/Writer
Since 7.1, Talend Data Mapper features a complete rework of the COBOL Reader/Writer. If you wish to migrate to the latest version of the COBOL representation, check the implementations.
Numeric control
The controls on numerics, particularly packed decimals, are now tighter. This implementation may result in failing maps. To fix this issue, new COBOL properties are introduced - Pad decimals on read with leading zeroes, Allow spaces for packed decimals, Allow any character in display decimals. For more information, see COBOL representation properties.
Byte array or Input stream
The COBOL reader only accepts either a byte array or an input stream. If you connect a tFileInputRaw set to read data as String and connect a ttHMap with a COBOL Reader configuration, this raises an exception.
