Overview

You can use this Snap Pack to consume one or more COBOL Copybooks and a data stream to produce a JSON formatted message containing the structured payload.

Prerequisites

None.

Supported Versions

• Cobol Mainframe - All versions.

• Cobol Open Systems - All versions.

Supported Copybook Structures and Payloads

• Copybooks contain multiple 01 records, and payloads contain multiple record types.

• Payloads with the following characteristics:

  • Fixed length

  • CRLF delimited

  • LF delimited

  • Continuous stream (no delimiter)

  • Mainframe variable record length file (4-byte length field with a 2-byte length, which is the length of the payload plus the 4-byte RDW followed by 2 bytes of hex ‘00’s).
    A variation on the mainframe variable record length file where:

    • A 4-byte length consisting of a 2-byte length field that is byte-swapped for intel systems. This does not include the length of the 4-byte word. To be specific, it contains the length of the payload following the 4-byte length field.

    • The last two bytes of the length field are hex ‘00’s.

• Big-Endian or Little-Endian payload.

• All standard COBOL types including packed and zoned decimal.

• COBOL array constructs such as ‘occurs’ and ‘occurs depending on'.

• COBOL Redefines.

• Payload encoded in EBCDIC (Extended Binary Coded Decimal Interchange Code) or any encoding supported by Java.
