Db2 coprocessor conversion considerations

When you upgrade programs that use the Db2® precompiler to instead use the Db2 coprocessor, you need to be aware of differences in language elements and in code-page conversions.

Consider the following topics:

  • Db2 coprocessor integration
  • Language elements
  • Code-page conversion

Starting with Db2 Version 8 you can no longer use the Db2 precompiler for OS/VS COBOL programs. In addition, you cannot mix OS/VS COBOL with Enterprise COBOL. Therefore, if a program needs to be changed, it must be upgraded to Enterprise COBOL.
