Use of Basic Mapping Support (BMS)
- Is HostBridge sensitive to changes in the location of fields, or the value of literals, on a BMS map?

- Using IBM’s definitions, is HostBridge a first, second or third generation connector?
- How does TIBCO connect to Hostbridge?
- Does HostBridge return Data to TIBCO in XML format when using the LINK/ECI interface?
- Can HostBridge still invoke a terminal-oriented transaction via the 3720 Bridge when using the LINK/ECI interface between TIBCO and HostBridge?
- Is the size of the COMMAREA still limited to 32K when using the LINK/ECI interface between TIBCO and HostBridge?
- Can TIBCO use HTTP to connect to HostBridge from a middle tier server or from Substation on OS/390?
