The IDS_INITIALIZATION_OFFSET strings are the set of initialization commands sent to the gateway after each connection has been established. These typically set the gateway to a "raw" SQL conversion mode, set various datatype conversions, set gateway defaults to ODBC defaults, and so on. Each string is sent as one language event. If the gateway can support multiple statements, it is more efficient to put them in a single string so that they are sent to the gateway as a single language event.
