The system() function was attempted in an AMODE 64 application while running POSIX(ON), but environment variable __POSIX_SYSTEM=NO is also in effect. This combination asks for the ANSI system() behavior. The ANSI system() behavior is not supported in an AMODE 64 application. This restriction prohibits nested enclaves, and the execution of TSO commands, EXECs, and CLISTs.
No action can be taken. The function is not supported.
