In BSAM, you can use the DCBE option, FIXED = USER, to mean that the caller has taken care of page fixing all the data areas. Use the FIXED = USER option in any of the following situations:

• The BSAM caller has APF authorization.
• The BSAM caller is in system key.
• The BSAM caller is in the supervisor state.

For more information about the FIXED = USER option, see z/OS DFSMS Macro Instructions for Data Sets.
