Generating a reentrant program executable for C or C++

To generate a reentrant C object module, follow these steps:

1. For C, if your program contains external data, compile your source files using the RENT compiler option. For C++, compile your source files; by default the compiler builds reentrant programs using constructed reentrancy. See z/OS XL C/C++ User's Guide for more information.
2. To produce an executable program:
   • If the target data set is a PDSE or HFS, use the binder to combine all of the input into an executable program
   • If the target data set is a PDS, use the prelinker to combine all of the input before passing it as input to the binder. You cannot run an object module through the prelinker more than once. Also, you must link-edit using the same platform you used for the prelink step.
3. To get the greatest benefit from reentrancy, install your executable program in one of the locations listed in Installing a reentrant load module.
