Parameter list contents

Register 1 contains a pointer to the exit parameter list, PWX2, which is mapped by macro ICHPWX2 in SYS1.MODGEN. See z/OS Security Server RACF Data Areas for a mapping of the PWX2 data area.

Not all parameters in the parameter list are available to all invokers. Table 1 summarizes which parameters are available depending on the RACF® component that invoked the exit.
