IBM SC34-6814-04 - Manual (Page 810)

General notes:
The following comments apply to the chapters in Part 7 of this book:
v The only aspects of CICS security processing covered are:
– Invoking a user-written external security manager.
– Writing a “good night” transaction.
Customization of password expiry templates for HTTP basic authentication, which
is an element of CICS Web support, is covered in the CICS Internet Guide. For a
comprehensive view of security processing using the Resource Access
Control Facility (RACF) product, see the CICS RACF Security Guide.
v Upon return from any customer-written program, CICS must always receive
control in primary-space translation mode, with the original contents of all access
registers restored, and with all general-purpose registers restored (except for
those which provide return codes or linkage information).
For information about translation modes, refer to the IBM ESA/370 Principles of
Operation manual.
