ADCD refers to a special distribution of z/OS provided by IBM for development, testing, and educational purposes. It is not a production-level system but a pre-configured, turnkey environment that runs on emulators like ZD&T (Z Development and Test Environment) or on supported mainframe hardware.
Many ADCD users compile C/C++ applications using LE (Language Environment). If a C routine passes a pointer to a local stack variable instead of a heap-allocated block to a system service that expects a FREEMAIN-able address, the result is a 113-13 abend.
