The Connect ETL mainframe compatible sort allows you to use Connect ETL to seamlessly execute selected JCL sort steps in your Open System environment. The following sort control statements, statement parameters, and PARM options are currently supported. Please refer to a mainframe sort manual for a detailed description of the parameters and options. When a sort step contains an unsupported parameter or option, Connect ETL issues a warning, and may either continue or abort, depending on the error.
