Invoking the security exit

The security exit program is invoked as follows:
CALL HFM1SXT (FM_SECURITY_PARAMETERS, FM_SECURITY_WORKAREA, FM_IMS_SECURITY_PARAMETERS)
The security exit interface parameters are:
  • The security parameter list passed to the security exit. This parameter list is documented in the following pages.
  • A security area work area which is a 256-byte area initialized to binary zeroes. This area is unchanged by ZDT/IMS and can be used to pass information between multiple calls to the security exit.
  • IMS™ security parameters which are passed to the IMS Initialization and Termination exits.
