The COBOL representation is intended as an alternative to using the Flat representation when working with binary EBCDIC files.

Using the COBOL representation provides better performance but has some restrictions compared to the Flat representation.

In particular, the following restrictions apply to the COBOL represenation.

  • It does not support Initiators/Terminators (they are ignored if you set them).

  • It does not support offsets.

  • It does not support non binary input files.

  • It does not support newline characters.

For this reason, the COBOL representation is not the default representation for working with COBOL data types. When you import a COBOL copybook, the default representation remains Flat.
