These exit classes allows users to access data and modify it. This user-exit can be used to modify data saved to and retrieved from a database. It currently handles Strings only. This is sometimes required for some languages where strings stored in a database may need to be presented differently for display. For example DB2 accessed via JDBC can save and retrieve different results from DB2 accessed on the mainframe if the latter is set to an encoding different from that of the JVM.
