Fixed-point overflow z/OS Language Environment Writing Interlanguage Communication Applications SA38-0684-00 |
|
The XL C++ compiler assumes that fixed-point overflow exceptions will be handled by S/390® hardware, while the PL/I compiler assumes that the runtime library will process these exceptions. Therefore, if a C++ to PL/I ILC application incurs a fixed-point overflow, Language Environment will try to handle this exception in the runtime library. This will result in increased CPU utilization compared to an application using only C++. |
