How Do We Code Segments In Ims Dc Program? |

Answer» The messages that application programs receive and send consist of one or more message SEGMENTS. Single-SEGMENT messages contain only one segment. A single GU and ISRT call is used for processing single segment message. For multisegment input message processing, the application program USES a GU call to retrieve the FIRST segment of a message, and GN calls to retrieve the remaining segments. For multisegment OUTPUT messages, the application program uses multiple ISRT calls. The messages that application programs receive and send consist of one or more message segments.
