What does HostBridge use to generate its XML output?
When a CICS transaction issues a BMS call (e.g., SEND MAP), it specifies the name of the map and the data to be displayed. CICS checks to see if the transaction is running under 3270 Bridge. If so, CICS uses the map name to retrieve the ADSD information out of the appropriate load module. CICS then passes control to the registered bridge exit (i.e., HostBridge), providing it with the ADS and the ADSD (as well as control/status information). HostBridge uses the ADSD to obtain the field names; it uses the offsets within the ADSD to extract the field values out of the ADS. HostBridge then expresses these field name/value pairs (as well as important control information) within an XML document.
