KWIK-KEY/KWIK-LOAD 4.1 Release Notes

Released On: 10/27/2025

Enhancements:

• Implements the MacKinney License Key (MLK) product to control licensing. Zapping the annual password is no longer required.

• Normally, MLK will change the return code of a step to 4 when the password is about to expire, and to 6 when the password has expired, but is still within a 15-day grace period. Condition checking in JCL does not always handle a non-zero return code well. A zappable installation option allows you to specify that the return code be set to 0 until the license and grace period have expired.
