Conversion from ASCII to EBCDIC
Java is a product which was developed in an ASCII world (Unix systems and Windows systems). In an operating system based on EBCDIC code, therefore, you will notice a number of peculiarities when working with code sets, localized streams, print streams, and standard streams, for example. These peculiarities are described in this documentation.
JNI under BS2000
This documentation also describes a number of special features that you as a user of Java Native Interfaces (JNIs) in BS2000 must take into consideration, such as the use of Java data types in C and the dynamic loading of native methods.
