This topic contains Product-sensitive Programming Interface and Associated Guidance Information.
When CICS® invokes the ESM, it passes information about the current CICS environment, for use by an ESM exit program, in an installation data parameter list. How your exit programs access the installation data parameter list depends on the ESM you are using. The ICHxxxxx interfaces defined in Table 1 apply only to RACF®. For programming information on non-RACF interfaces, see the CICS Customization Guide.
