Displaying a list of compile units known to z/OS Debugger

This topics describes what to do if you want to know which compile units are known to z/OS® Debugger. This is helpful if you have forgotten the name of a compile unit or the load module that a compile unit belongs to.

To determine which compile units are known to z/OS Debugger, do one of the following options:

  • Enter the LIST NAMES CUS command.
  • If you are debugging an assembler or disassembly program, enter the SET DISASSEMBLY ON or SET ASSEMBLER ON command, then enter the LIST NAMES CUS command.

After you run the LIST NAMES CUS command, z/OS Debugger displays a list of compile units in the Log window. You can use this list to compose a SET QUALIFY CU command by typing in the words "SET QUALIFY CU" over the name of a compile unit. Then press Enter. z/OS Debugger displays the command constructed from the words that you typed in and the name of the compile unit. Press Enter again to run the command.

For example, after you enter the LIST NAMES CUS command, z/OS Debugger displays the following lines in the Log window:

USERID.MFISTART.C(CALC)
USERID.MFISTART.C(PUSHPOP)
USERID.MFISTART.C(READTOKN)

If you type "SET QUALIFY CU" over the last line, then press Enter, z/OS Debugger composes the following command into the command line: SET QUALIFY CU "USERID.MFISTART.C(READTOKN)". Press Enter and z/OS Debugger runs the command.

This method saves keystrokes and reduces errors in long commands.
