The LIST command displays information stored in the performance data file. If you specify data-kind parameters, it displays all corresponding performance or coverage data records from the file. Thus, you can inspect the raw performance or coverage data gathered by the Collector. If you specify the appropriate qualifiers, the LIST command displays other information stored in the performance data file (see qualifier list). You must always request at least one kind of information from the LIST command. The output of the LIST command is often extensive. You can stop the LIST output by entering CTRL/C. The LIST output can be sent to the printer with the PRINT command or written to a file with the FILE command. If you write the LIST output to a file, you can use it as input to your own data reduction programs.
