Natural Optimizer Compiler Version 8.3.2 is available from Natural Version 8.2.5 onwards.
For the changes in installation, see Installing the Natural Optimizer Compiler Version 8.3.2 on z/OS and z/VSE in the Natural Installation documentation.
This section describes the new features of Natural Optimizer Compiler Version 8.3.2.
Architecture levels are used to exploit new instructions available with IBM hardware facilities in order to enhance the performance of generated code (see the related literature from IBM).
The ARCH option of Natural Optimizer Compiler Version
8.3.2 now also supports IBM architecture level 10 on z/OS and z/VSE
platforms.
When using architecture level 10, you can improve the performance of specific Natural statements with arithmetic variable operations by up to 40 percent. For the requirements and restrictions that apply, see the sections ARCH Option and Support for Architecture Level 10 in Natural Optimizer Compiler Version 8.3 - Documentation Updates in the Natural Optimizer Compiler documentation.
Natural Optimizer Compiler Version 8.3.2 now also generates optimized code for Natural statements that contain Unicode operands.
In addition, the new UNICC option is provided to meet
specific generation requirements for IF and DECIDE
statements with Unicode operands.
