A New user-replaceable program DFHAPXPO is provided.
DFHAPXPO is loaded during the PIPI preinitialization phase of each Language Environment® enclave where C or C++ programs compiled with the XPLINK option are to be run. It allows you to alter the default Language Environment run-time options. See the z/OS® Version 1.4 Language Environment Programming Guide, SC22-7561, for details of the Language Environment options that can be reset. The program must be written in Assembler language.
