This chapter describes the ILE COBOL language extensions that support workstations and program-to-program communication.
The TRANSACTION file organization allows an ILE COBOL program to communicate interactively with:
The AS/400 system permits you to communicate with a program or device (such as Asynchronous communication types) on a remote system. For a detailed discussion of these devices, see the ICF Programming manual
ILE COBOL TRANSACTION files are usually externally described. If these files are program-described, only simple display formatting can be performed. For more information about using program-described display files, refer to the Database and File Systems category in the iSeries 400 Information Center at this Web site -http://publib.boulder.ibm.com/pubs/html/as400/infocenter.htm.
An ILE COBOL TRANSACTION file usually uses an externally described file that contains file information and a description of the fields in the records. The records in this file can be described in an ILE COBOL program by using the Format 2 COPY statement. Refer to the WebSphere Development Studio: ILE COBOL Reference for more information about the Format 2 COPY statement.
Do not send packed or binary data (COMP, COMP-3, or COMP-4) to a display station as output data. Such data can contain display station control characters that can cause unpredictable results.
