Customizing z/OS Debugger User Exit Data Set

The z/OS® Debugger User Exit Data Set utility creates a user exit data set that is used by the z/OS Debugger Language Environment® user exit to start a debug session. You can set the default value of the data set naming pattern for the users by taking the following steps:
  1. Review the parameter described in Table 1. Verify that you have all the information to specify the value for the parameter. See the EQAZDSYS member of the hlq.SEQATLIB data set for the parameter and the syntax convention.
  2. Edit the EQAZDSYS1 member of the hlq.SEQATLIB data set. Modify the parameter required by your site. You can add parameters by doing one of the following alternatives:
    • Use the INCLUDE ‘any.data.set.name’; statement to include statements from a data set that you created.
    • Use the INCLUDE membername; statement to include parameters from other members in the hlq.SEQATLIB data set.
    If your application programmers use terminals that cannot display text in mixed-case English, enter parameters and their values in uppercase English.

See Specifying the TEST runtime options through the Language Environment user exit for how the user exit data set is used.

Table 1. Parameter for the z/OS Debugger User Exit Data Set option of IBM z/OS Debugger Utilities
Name of parameter Description
uepnmp The naming pattern of the user exit data set.

The utility builds a data set name by using the naming pattern that is used when the option is selected for the first time. The data set name and modification (if user modifies it) are consistent across the IBM® z/OS Debugger Utilities sessions.

The following list describes the rules of using the token:
  • The &USERID token is replaced with the value from the SYSPREF or SYSUID system variable.
  • The &PGMNAME token is not supported.
  • If the parameter does not exist, the default naming pattern is used: 
    &USERID.DBGTOOL.EQAUOPTS
1 USERMOD EQAUMOD6 is provided for updating EQAZDSYS. See SMP/E USERMODs in the IBM z/OS Debugger Customization Guide for an SMP/E USERMOD for this customization.
